Application: plasma-desktop (0.3)
KDE Platform Version: 4.4.67 (KDE 4.4.67 (KDE 4.5 >= 20100310)) (Compiled from sources)
Qt Version: 4.6.2
Operating System: Linux 2.6.31-14-generic i686
Distribution: Ubuntu 9.10

-- Information about the crash:
- What I was doing when the application crashed:

Selected an item on task bar

- Unusual behavior I noticed:

Plasma's bottom bar re-started and crash dialog opened, the active window was OpenOffice, dolphin and google-chrome were running, I've selected chrome on the taskbar when the crash happened. Cannot reproduce again, this was a random crash.




The crash can be reproduced some of the time.

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