Description of problem:
Hm. I pressed Escape in a chat window Gajim. And FWIW my gnome-settings-daemon is dead due to some other bug where it consumes all CPU.
Reproducing the issue is a bit tricky as one has to be quick closing the window. I.e. double click a roster item and then quickly press escape. If you're lucky, Gajim crashes. If not, rinse and repeat. After a couple of times, Gajim crashes for me.

There is already something in b.f.o: bug 551834
