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 x86_64
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed:
Just starting my computer with Kubuntu 10.10.

- Custom settings of the application:
I added a Search and Launch plasmoid on the dashboard (which won't even display anymore) and plasma carshes on startup eversince. But I'm not sure plasma crashing has something to do with it...

The crash can be reproduced every time.

-- Backtrace:
Application: Outil de gestion de fenêtres Plasma (plasma-desktop), signal: Segmentation fault
