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 2.6.31-desktop-0.rc8.1mnb i686
Distribution: "Mandriva Linux 2010.0"

What I was doing when the application crashed:
I was using ktimetracker simultaneously, on the same std.ics file. I think it caused the crash. Whereas it may be an unsupported way of working, the program shouldn't crash !
