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:
- What I was doing when the application crashed:
I was downloading and installing new plasmoids.
- Unusual behavior I noticed:
plasmoïd's icons disapeared each time I installed or uninstalled a plasmoid and don't show themselves again, i was forced to close Plasma and open it again to see the icons.
Moreover Plasma can't add a layout since i download the first plasmoid i want

-- Backtrace:
Application: Espace de travail Plasma (plasma-desktop), signal: Segmentation fault
