Application that crashed: kontact
Version of the application: 4.3.0
KDE Version: 4.3.00 (KDE 4.3.0)
Qt Version: 4.5.2
Operating System: Linux 2.6.28-14-generic i686
Distribution: Ubuntu 9.04

What I was doing when the application crashed:
Calendar is syncing with Google Calendar using GCALDaemon. Added the 'Next Event' Google Labs functionality to the calendar on Google's site and Kontact crashed immediately after.
Akonadi had been restarted just before this happened which may have also caused the crash.
