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 2.6.30-ARCH i686

What I was doing when the application crashed:
akregator randomly crashes while i try to open a feed from http://heute.de. sometimes it works, and sometimes it fetches the feeds and displays them as "unread" - when i try to open them kontact (in which i run akregator) crashes together with akregator.
