Bug 220909

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 2.6.28-17-generic x86_64
Distribution: Ubuntu 9.04

What I was doing when the application crashed:
Was deleting an empty folder on my plasma desktop widget, and plasma crashed. Probably because it was trying to view the deleted folder.

 -- Backtrace:
Application: Plasma Workspace (kdeinit4), signal: Segmentation fault
