Application: plasma-desktop (0.3)
KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-25-generic i686
Distribution: Ubuntu 10.10

-- Information about the crash:
When I started Kubuntu, KDE went off and show me an error message. The last time I used KDE as usually, I put an "activity" working and show me the same message.
- Unusual behavior I noticed: Activity causes that error

The crash can be reproduced every time.

-- Backtrace:
Application: Área de trabajo de Plasma (plasma-desktop), signal: Segmentation fault
