Bug 301167

Application: plasma-desktop (0.4)
KDE Platform Version: 4.7.4 (4.7.4) (Compiled from sources)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-20-generic i686
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed: I was adding the system trayu to the default panel after the previous crash. The KDE repeatedly randomly changes session to GNOME.

The crash can be reproduced every time.

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