Description Redash Rajal 2011-03-29 22:26:19 UTC

Application: plasma-desktop (0.4)
KDE Platform Version: 4.6.1 (4.6.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-28-generic i686
Distribution: Linux Mint 10 KDE

-- Information about the crash:
- What I was doing when the application crashed: opened up the lid to "wake up" the computer, when the computer came back on the Crash Reporting Assistant was up.

- Unusual behavior I noticed: Other then that. NONE.

The crash can be reproduced every time.

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