gnome-settings-daemon fails with libgstlibvisual.so error

Confirmed and a libvisual-0.4-plugins removal solves this seg fault.

Confirmed, removing libvisual-0.4-plugins restores correct theme settings and allows gnome-settings-daemon to load

Confirmed as well. (8.10 beta amd64)

removing /usr/lib/gstreamer-0.10/libgstlibvisual.so fix problem.

Confirmed as well. (8.10 beta), removing /usr/lib/gstreamer-0.10/libgstlibvisual.so fixed problem.

This is a regression since libvisual-0.4-plugins_0.4.0.dfsg.1-2_i386.deb

confirmed... removed libvisual-0.4-plugins & all is well. wish i could remember why it was installed in the first place, as no one i know had it on their system.

Hi,

This is pretty odd. The problem seems to be with the nastyfft plugin.
It seems to be corrupting the info object at initialisation time.

The -2 version still works, but recompiling it under Intrepid breaks it
again.

Thanks,

James

I built 0.4.0.dfsg.1-2 on current intrepid and get the crash, too, so it's not a regression in the recently changed source bits, but due to building to newer libraries.

BTW, it's quicker to debug this with calling "gst-inspect-0.10" instead of gnome-session-daemon.

I verified that building with --disable-nastyfft works around the crash, so that would be an acceptable solution for intrepid release.

I'm going to debug the actual crash now.

I have encountered this bug as well, and verified removing libvisual plugins fixed.
I'm running Ubuntu 8.10 on x86 32bit. (Thinkpad T61).

gnome-settings-daemon worked fine until the last reboot due to a slew of updates for Ubuntu 8.10.
I had restarted this morning due to those fixes, and then had this problem.
Sounds like there is a good handle on the problem.

Hey there, pushed the fix in libvisual-plugins 0.4.0.dfsg.1-2ubuntu4 in intrepid (pending review) and my ppa (still being built). https://launchpad.net/~lool/+archive

This bug was fixed in the package libvisual-plugins - 0.4.0.dfsg.1-2ubuntu4

---------------
libvisual-plugins (0.4.0.dfsg.1-2ubuntu4) intrepid; urgency=low

  * New patch, 60_no-const-vispluginfo-in-nastyfft, the static VisPluginInfo
    in nastyfft was declared as const, but libvisual write to its refcount
    when it visual_object_unref()s it (nasty!). This is broken at various
    levels: libvisual shouldn't be writing to this static plugin which is
    allocated by a dlopen()ed plugin, and it should also honor the "const
    VisPluginInfo" API... Anyway, nastyfft was the only occurrence and this
    fixes the crash for now; LP: #287448.

This breaks pidgin as well BTW:

$ pidgin

ERROR: Caught a segmentation fault while loading plugin file:
/usr/lib/gstreamer-0.10/libgstlibvisual.so

Please either:
- remove it and restart.
- run with --gst-disable-segtrap and debug.

Moved libgstlibvisual.so out of the way and pidgin starts up.

Loïc's ppa libvisual-0.4-plugins_0.4.0.dfsg.1-2ubuntu4_amd64.deb
fixes this bug for me, cheers

Echo > "Nema problema" also on 32 bit, ppa version

Thanks ! ;)

I was having a similar bug in Songbird and simply did sudo apt-get remove libvisual-0.4-plugins and everything was fine again!

Issue is occurring on Ubuntu 10.4 (as of today, was working fine yesterday)

$ pidgin

ERROR: Caught a segmentation fault while loading plugin file:
/usr/lib/gstreamer-0.10/libgstlibvisual.so

Please either:
- remove it and restart.
- run with --gst-disable-segtrap and debug.

Moved or removing libgstlibvisual.so out of the way and pidgin starts up.

This started happening after I upgraded to Ubuntu 10.10. Previously, pidgin was working.

pidgin
ERROR: Could not load classifier cascade /usr/share/opencv/haarcascades/haarcascade_frontalface_alt2.xml

ERROR: Caught a segmentation fault while loading plugin file:

Please either:

Removal of /usr/lib/gstreamer-0.10/libgstlibvisual.so worked for me as a workaround. Interestingly this does not happen on my likewise 64-bit Ubuntu 10.10 laptop, likewise with Pidgin 2.7.5, only the desktop. Also, it did not happen for Pidgin 2.7.3 on either machine.
