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 2.6.31-20-generic x86_64
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
Attempting to configure access to a DAViCal server (so far unsuccessful). This crash happened after a few attempts at creating/updating an event in that calendar. Currently configured to access directly, not via Akonadi.  (I cannot see how to configure Akonadi to to talk to the server, although it is supposed to be the way to do it)

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