Application that crashed: kontact
Version of the application: 4.3.4
KDE Version: 4.3.4 (KDE 4.3.4)
Qt Version: 4.5.3
Operating System: Linux 2.6.32-trunk-amd64 x86_64
Distribution: Debian GNU/Linux unstable (sid)

What I was doing when the application crashed:
After a few hours, Akregator's indexing goes wrong and one of the feeds shows -1 total (so 0 unread means there's one unread. Then undated duplicate entries appear at the top of the list of articles (usually all the same article - there were about 10 when I looked at 03.00, then by 06.00 Kontact had crashed. This bug has been around for months through several versions of KDE 4.
