Application that crashed: kontact
Version of the application: 4.3.1
KDE Version: 4.3.1 (KDE 4.3.1)
Qt Version: 4.5.2
Operating System: Linux 2.6.28-15-generic i686
Distribution: Ubuntu 9.04

What I was doing when the application crashed:
I chose a massage on an imap-server to be filtered as a spam. Instead of moving it to a spam folder on the server (filtering rule is defined in such a way) Kmail waited for a while and then crashed. 

 -- Backtrace:
