Application that crashed: korganizer
Version of the application: 4.3.1
KDE Version: 4.3.1 (KDE 4.3.1)
Qt Version: 4.5.2
Operating System: Linux 2.6.30-6 i686
Distribution: Debian GNU/Linux testing (squeeze)

What I was doing when the application crashed:
calendars are remote and if i click on an appointment that's cached locally while the organizer is still loading the remote calendars, the whole organizer crashes. i can reproduce this.

 -- Backtrace:
