Application that crashed: ktorrent
Version of the application: 3.3
KDE Version: 4.3.5 (KDE 4.3.5) "release 0"
Qt Version: 4.5.3
Operating System: Linux 2.6.31.12-0.2-desktop x86_64
Distribution: "openSUSE 11.2 (x86_64)"

What I was doing when the application crashed:
Ktorrent is seeding multiple torrents for me, and loading automatic RSS feeds. A new feed was auto-added to the torrents and had been downloading for a while, until the ktorrent crashed by itself.

 -- Backtrace:
