Application: plasma-desktop (0.4)
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-8-generic x86_64
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed:

I added "Asphyxia" startup screen. When I ran the test, i received communicate, that it didn't pass the test, but I left this startup screen selected anyway. I installed also some skins. I also installed, and added "Nixie Clock" plasmoid, which in few earlier releases of Kubuntu didn't work on my machine. This time however it seemed to work just fine.

- Unusual behavior I noticed:

After next reboot everything worked as usual, except of plasma desktop. All desktops were black, and even after choosing different startup screens, and different skins plasma didn't run. Now every system startup I receive a bug report window, and the "run application again" button is frozen there. However everything else is usable as normal.

- Custom settings of the application:

+ Setted "Asphyxia" startup screen.
+ Added multiple plasma skins
+ Installed some desktop plasmoids.

The crash can be reproduced every time.
