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 2.6.28-15-generic i686
Distribution: Ubuntu 9.04

What I was doing when the application crashed:
Tried to rename a folder with F2 leads to crash of plasma, just look for simple file operations in desktop...

another bug:
if i move mouse over folder a popup with the content raises.
when i right-click a containing file, i can choose rename, but if i choose it all disappears and i cannot rename...
