Bug 223561

Application that crashed: ktorrent
Version of the application: 3.3.2
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.3
Operating System: Linux 2.6.31.6-desktop-1mnb x86_64
Distribution: "Mandriva Linux 2010.0"

What I was doing when the application crashed:
ktorrent was downloading files when it crashed. No ktorrent windows where open and there was only the icon in the panel.

It is the first time ktorrent has crashed on me like this and I don't know how to reproduce it.
