Application: plasma-desktop (0.3)
KDE Platform Version: 4.4.1 (KDE 4.4.1)
Qt Version: 4.6.2
Operating System: Linux 2.6.32.9-70.fc12.i686 i686
Distribution (Platform): Fedora RPMs

-- Information about the crash:
first thing i do when i log in, is change my screen resolution back to what i last had it at.
normally plasma crashes, and the desktop stays black, with  applets up in the top corner.
this happends 80% of the time, and does not seem to be related to how quick i am, to change my resolution at startup.
had to use ctrl+alt+backspace to restart X a while ago, but now plasma is restarting itself...

The crash can be reproduced some of the time.

 -- Backtrace:
