Comment 3 for bug 455943

Doesn't seem to be something in the python stack - I have matching stacks on both machines. Nothing's changed in the gwibber in Factory - I'm actually using the trunk version from my own project on both my machines.

Something must have changed 'higher up' and I suspect it may be something to do with the xorg driver. I recall that the xorg stack in X11:Xorg changed so that on my nvidia machine, I could no longer compile the (slightly antiquated) version I was using and had to switch to the official packages - something about an ABI change.

I know it's a long shot but wondering whether sndirsch can help?
