Comment 21 for bug 628372

I have figured out the origin of this bug (at least for me). The bug appeared for me yesterday because I had just installed unity (for fun) which brought in a bunch of zeitgeist packages. When I removed unity and all the zeitgeist packages, this bug goes away. In particular, libzeitgeist-gio libzeitgeist-1.0-0 seem to cause the trouble.

I can reproduce the bug 100% of the time and reproduce the fix every time by reinstalling unity and then removing it (and the zeitgeist packages).
