Bug Description

I am using ubuntu 8.04 and epidermis 0.2.

Here is the output from the command line

/usr/lib/python2.5/site-packages/epidermis/epidermis.py:287: GtkWarning: gdk_window_set_icon_list: icons too large

Are you using the following repo: http://download.tuxfamily.org/epidermis/ghns/downloads.xml
Put that address under Repo URL in Settings.
Can you access the Internet normally? What happens if you open the URL above in a browser?

I get the same error, and (for me at least) the problem is with using Epidermis through a proxy. This is related to bug 313456, but the statement that Epidermis uses urllib is wrong. In loadrepo.py it extensivly uses httplib, which does not have automatic proxy detection.

I have been trying to fix this on my own, but it seems that loadrepo.py uses the http headers to determine whether the repository has been updated and I can't see a way to convert this functionality to urllib. Any suggestions?

OK, I found out that it can be done by using urllib2 instead of urlib. In urllib2.urlopen() you can pass a urllib2.Request object which takes HTTP headers as an argument in the constructor.

I also found out that httplib is used in managepigments.py (and possibly more places?), making it impossible to download and install themes when behind a proxy.

Well spotted skaggmannen. I used httplib in order to send headers with requests for http files. I didn't realise that the url passed to urllib2.urlopen() could be either a string or a urrlib2.Request object.
For the record, Epidermis does use urllib, it just uses httplib in addition.
The plan now is to rewrite any code that uses httplib and use urllib2 exclusively in Epidermis.

A fix has been committed to the trunk, could someone with access to a proxy test it?
