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 2.6.31-17-generic i686
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
Just shortly after login plasma craches...

Btw.: When starting plasma-desktop after that crash, it takes about one minute before everything is up and runnning...

 -- Backtrace:
