Sentry Crash Report:

Description Rodislav Moldovan 2011-06-21 10:25:28 UTC 
Application: plasma-desktop (0.4)
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-8-generic-pae i686
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed:
Accidental right click on panel instead of tasks manager applet to change some settings, after left-click in space to close contextual menu of the panel - something crashed, I gues it was the panel. 

That happens 3rd time since I've installed. I have latest updates installed on my system.

The crash can be reproduced some of the time.

-- Backtrace:
Application: Învelișul de birou Plasma (plasma-desktop), signal: Segmentation fault
