After upgrading to pygtk-2.10.1-r1, the deskbar-applet crashes on text entry or bringing up the preferences window, or just about anything. Since it's a crasher, I've up the severity to major. Reverting back to pygtk-2.10.1 causes it to work fine again. I think the tree-model fix needs double checking. Perhaps the package could be masked until the issue is sorted out? This will probably be the cause of: http://bugzilla.gnome.org/show_bug.cgi?id=358932 http://bugzilla.gnome.org/show_bug.cgi?id=359111 and several other gnome-filed bugs dated after the 1st of October (when the latest pygtk was added).
Reading bug 148247 it suggests that gajim is also affected.
I've masked that pygtk.
