Sentry Crash Report:

Description Kirk M 2009-12-22 03:38:54 UTC 
Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.3.4 (KDE 4.3.4)
Qt Version: 4.5.3
Operating System: Linux 2.6.26.8.tex3 i686

What I was doing when the application crashed:
Using KDE 4.3.4 with PCLinuxOS 2009.2.

Right-clicked on Desktop and accidently clicked on "Undo Trash" when there was no trash in the "Trash Can". The tray based "Info" icon popped up a black box with some text inside but the Plasma Desktop crashed too quickly to read. The Plasma Desktop recovered (restarted?) quickly without any intervention by me (less than 3 secs). The big reporter popped up and suggested I install GDB. I did this and was able to report.

Comment 1 Kirk M 2009-12-22 03:41:22 UTC 
Minor correction: Where it states "big reporter" should read bug "reporter".
Comment 2 Dario Andres 2009-12-22 14:21:14 UTC 
This is probably related to bug 212750 and bug 168427
