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 2.6.31-16-generic x86_64
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
There was a system upgrade that took place . After the upgrade, the system asked to be rebooted. After the reboot, the system opened two instances of Kontact and when I closed one of them, that's when the crash occurred.

 -- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
