Application: plasma-desktop (0.4)
KDE Platform Version: 4.7.1 (4.7.1) (Compiled from sources)
Qt Version: 4.7.4
Operating System: Linux 3.0-ARCH i686
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed:
I logged off and plasma-desktop crashed. This seems to happen most of the time.
I rebuilt the archlinux packages without stripping debug symbols so that I can submit a report the next time it crashes.

The crash can be reproduced some of the time.

-- Backtrace:
Application: Plasma Desktop Shell (kdeinit4), signal: Segmentation fault
