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:
I renamed a folder in the Desktop widget. The folder seemded to get moved (copied?) to the new folder, the plasma desktop then crashed and reloaded itself.

 -- Backtrace:
