Application that crashed: kontact
Version of the application: 4.3.2
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-14-generic i686
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
I woke my computer from hibernation and launched Kontact from krunner.  As far as I knew, Kontact had shut down normally quite some time before hibernation.  Akgregator would have ben running at hibernation time
