Bug 262378

Application: ktorrent (4.0.5)
KDE Platform Version: 4.5.4 (KDE 4.5.4) "release 9"
Qt Version: 4.6.3
Operating System: Linux 2.6.34.7-0.7-desktop x86_64
Distribution: "openSUSE 11.3 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:

Then computer was running "on idle" in the background (alongside hplip, pidgin, kmail, klipper, kmix, krandtray and other standard kde tray programs), the last program closed before was mplayer.
This has happened before, always when I was not actively using the computer.

The crash can be reproduced some of the time.

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