Bug 214978

Application that crashed: ktorrent
Version of the application: 3.3
KDE Version: 4.3.3 (KDE 4.3.3) "release 180"
Qt Version: 4.5.3
Operating System: Linux 2.6.31.5-0.1-default x86_64
Distribution: "openSUSE 11.2 (x86_64)"

What I was doing when the application crashed:
Ktorrent is saved in my profile session and when my profile is started, ktorrent starts as well. But It crashs. Some of the torrent are live and set to share.

 -- Backtrace:
Application: KTorrent (ktorrent), signal: Aborted
