Description Robby Engelmann 2011-01-21 08:19:23 UTC
Application: plasma-desktop (0.4)
KDE Platform Version: 4.5.95 (4.6 RC2)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-25-generic i686
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed:
Plasma crashed immediately after deletion of a calendar event in Kontact.

For me this happens very rarely, as I have KCalendar in extensive daily use and it was the first time plasma crashed on this action.

The crash can be reproduced some of the time.

-- Backtrace:
Application: Plasma Desktop Shell (plasma-desktop), signal: Segmentation fault
