Bug 283111

Application: plasma-desktop (0.4)
KDE Platform Version: 4.7.1 (4.7.1)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-12-generic i686
Distribution: Ubuntu oneiric (development branch)

-- Information about the crash:
- What I was doing when the application crashed:
refreshing the calendar.  
- Custom settings of the application:
set calendar in kontact to sync with google calendar using kdepim.  
on refresh, plasma desktop crashes.  either refreshing the calendar manual or automatic (every 5 minutes as default) will cause the crash.

The crash can be reproduced every time.

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