[SRU] unable to copy music from an MTP device

thank you for your bug report, I don't confirm this issue on my intrepid installation. could you get a rhythmbox --debug log? are you sure the device is not mounted by gvfs or an another software?

Running rhythmbox with --debug does not seem to give more information, still only the same warning about free space in /tmp appears in the --debug log at the moment I try to copy a music file from the MTP device.

However, I just found that it's still possible to copy one music from the computer to the MTP device, the only thing that doesn't work is copying to the computer, and it looks like it is caused by rhythmbox which is not able to write in /tmp folder. However I don't see why it is not able because I can do it without being root and /tmp permissions are the same as they were at initial installation.

The device is not mounted anywhere before rhythmbox start communicating with it. My MTP device shows a big icon when the computer is connected, and when there is communication with the computer and I only see that icon when rhythmbox starts.

Might or might not be related : rhythmbox used to work perfectly in the last weeks, but after some updates, MTP plugin was suddenly disabled. I re-enabled it, and since this I have this bug.

I was able to reproduce this problem on my laptop which is a clean intrepid alpha 5 install with all updates installed, so I doubt that this is something like a configuration problem. This laptop really has default ubuntu settings. Also, I'm able to access my MTP device without problems through gnomad2, so the device isn't the problem either.

The problem is reproducible directly in the intrepid alpha 5 LiveCD. Under hardy, Rhythmbox MTP plugin works perfectly.

confirmed and sent on http://bugzilla.gnome.org/show_bug.cgi?id=552614

I tried this today using rhythmbox version 0.11.6svn20081008-0ubuntu3 and received a different error message:

wonderwoman:[~] rhythmbox
PTP: Opening session

(rhythmbox:26860): Rhythmbox-WARNING **: filesystem root apparently doesn't exist!

It works for me, using a Samsung YP-U3, and rhytmbox 0.11.6svn20081008-0ubuntu3

When I try to play a song from the MPT device (zen vision M:) by adding it to the play que first, I see the following message (when rhythmbox is started through terminal:

(rhythmbox:16173): Rhythmbox-CRITICAL **: rb_player_gst_play: assertion `mp->priv->playbin != NULL' failed

When I try to transfer a song from MTP to /home folder, the progress bar gets stuck at 0%.
At my /home/music folder, a folder for Artist and a subfolder for Album are created, but no file is actually transfered.

I'm closing the kdepim task for this bug report since it seems to have been added in error.

suitable for SRU; not a blocker for final release.

Steve Langasek : Should I use standard SRU procedure [1] or what I've done so far is enough for this bug?

the bug needs to be updated to conform to the sru rules, if you don't do it somebody else will have to do the update

I tested rhythmbox_0.11.6svn20081008-0ubuntu4.1 and the bug isn't reproducible anymore. I see no regression and it's possible to copy to/from the device without any problem.

Using rhythbox_9.11.6svn20081008-0ubuntu4.1 I was still unable to copy music from an MTP device (a Creative Zen Microphoto) to my system. Here is the hopefully relevant output of 'rhythmbox -d':

Copied intrepid-proposed version to jaunty.

Testing again with rhythmbox version 0.11.6svn20081008-0ubuntu4.1 from Intrepid -proposed, after installing saivann's ppa version of rhythmbox and downgrading back to -proposed, I am able to copy files from my MTP device to my system. I consider the verification of the SRU to have passed.

I also installed the rhythmbox package from the proposed repository and verified that i'm able to play music from the mtp device, but i can't copy from the device to the computer. When i run with --debug, i get error messages very similar to those shown by Brian Murray above. I tried doing a purge/reinstall but that didn't make a difference.

This feature is not critical to me but i thought it might be helpful to have someone else testing. thanks to everyone involved in getting the proposed package uploaded.

dieterv : Are you sure that you are using the good version? What is the output of this command in a terminal? apt-cache policy rhythmbox

dieterv : Can you also make sure that your system is up to date? Specifically libmtp8

I did not check if there is a libmtp8 update in proposed, if so that could be the issue.

apt-cache policy output:

dieterv : You have latest versions, and if the rest of your system is up to date, I wonder where is the problem. Can you also post the outputs that you get in the terminal when running rhythmbox?

Here's what i see in the console (when running with --debug) after trying to drag something from the mtp device to my library :

dieterv : What happens if you boot ubuntu 8.10 final release Live CD, update rhythmbox to 0.11.6svn20081008-0ubuntu4.1 and try to reproduce the bug again. Does that works?

the issue could be due to an incorrect library location

Copied to intrepid-updates, it was confirmed to work for some people.

Saivann, i tried your suggestion and used the live cd and everything seemed to work fine.
I guess maybe one of these days i ought to do a clean install...

thanks and sorry for the trouble.

dieter

dieterv : No, thank YOU very much for your testing ;)

Hi, after upgrade from 8.04 to 8.10 rhythmbox does not longer shows my creative zen 1 GB when I plug It. The devices is correctly mounted by gnome, i can see the icon on the desktop and I get prompted if I want to open rhythmbox.

Is this a different bug or still related with this one?
Btw, I installed today's (nov 6th) updates, but no luck.

Thanks.

ps: if you need some debugging info,please let me know

Call me Ishmael : Indeed, this is a different bug since rhythmbox does not detect even seem to detect your device, which is a different behavior then the one described in this bug report. BTW, do you still have "MTP plugin" enabled in rhythmbox options? If yes, can you open a new bug report for rhythmbox? Thanks for your feedback!

Hi Saïvann
After the release upgrade MTP was not checked (it was in the 8.04, because I used rhythmbox to transfer files to the player)
I checked it but the Creative Zen is not detected. I have a 30GB Ipod (5th gen), which is correctly handled even in 8.10, but I know is taken by another plugin.
I'll file a new bug report, thanks!

Update, I found out that the bug has been already open: Bug #270203.
A fix has been already released but did not work for some guys, neither worked for me.
Let's wait :-)

Call me Ishmael : Mmh, bug #270203 status is set to fix released, I think you'd better open a new bug report with a mention about bug #270230 in your bug description. Also, the outputs of these commands in a terminal might be useful in that case :

lsusb
apt-cache policy rhythmbox

If I was you, I would also try to umount your MTP device before trying to access it through rhythmbox, just in case, because in my case, my MTP device is not mounted by GNOME and rhythmbox is the first thing that really communicates with it. In case you open a new bug report, please subscribe me (saivann) to the bug so I can maybe help you looking at this further. Thanks for your feedback!
