Bug 234625

Application that crashed: ktorrent
Version of the application: 4.0beta2
KDE Version: 4.3.4 (KDE 4.3.4)
Qt Version: 4.6.2
Operating System: Linux 2.6.30-2-amd64 x86_64
Distribution: Debian GNU/Linux testing (squeeze)

What I was doing when the application crashed:
Ktorrent was downloading a torrent. It crashed while it was running unattended. This seems to happen occasionally when at least one torrent is active.

 -- Backtrace:
Application: KTorrent (ktorrent), signal: Segmentation fault
