The program then restarts and everything looks normal again.
Comment 2 Peter Andreasen 2013-01-21 06:52:48 UTC
Update: After googling the problem I found a suggestion that an old ~/.config/Trolltech.conf could cause this. Since this is an upgrade Fedora 14 -> Fedora 18, I removed that file, and the crash has not happened since.
