Application: plasma-desktop (0.3)
KDE Platform Version: 4.5.00 (KDE 4.5.0)
Qt Version: 4.7.0
Operating System: Linux 2.6.32-24-generic i686
Distribution: Ubuntu 10.04.1 LTS

-- Information about the crash:
- Unusual behavior I noticed: after installation KDE 4.5 second copy of the Task Panel have appeared. If I choose Close Task Panel Plasma crashed and I can start it again not every time.

The crash can be reproduced every time.

-- Backtrace:
Application: Рабочее пространство Plasma (plasma-desktop), signal: Segmentation fault
