Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.2.96 (KDE 4.2.96 (KDE 4.3 RC2))
Qt Version: 4.5.0
Operating System: Linux 2.6.28-13-generic i686
Distribution: Ubuntu 9.04

What I was doing when the application crashed:
I rename a folder(with dolphin) and cut/paste it into another partition(in a folder view). That operation failed because it kept the previous folder name(not the renamed one), after that I did a cut/paste again(as before, from dolphin to a folder view) and the plasma desktop crashes. To see the desktop I used the dashboard in the taskbar.
