Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-14-generic x86_64
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
When I login to my kde it plasma-desktop crash. Sometimes It automatically restart, sometimes not. Sometimes I noticed that I have to login again becuase it auto-exit kde.

I noticed that it happens more often when I'm on batteries (but not sure about that)
