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 2.6.30-020630-generic x86_64
Distribution: Ubuntu 9.04

What I was doing when the application crashed:
I have read some rss feeds when I clicked on the top feed (only heppened there until now) there were some entries marked as new although the feed had no new posts. The each of the new posts was shown twice. When I clicked on one of the "new" posts kontact crashed.

I'm on Ubuntu 9.04 64Bit with Kubuntu backport for kde 4.3 from PPA repository.
