Application: ktorrent (4.0.3)
KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-6.dmz.2-liquorix-686 i686
Distribution: Ubuntu maverick (development branch)

-- Information about the crash:
- What I was doing when the application crashed:
I have two torrent files, that are merged by ktorrent. While deleting torrent and his data (shift+del) ktorrent crashed.

The crash can be reproduced every time.

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