Application: ktorrent (4.2)
KDE Platform Version: 4.8.3 (4.8.3) "release 501"
Qt Version: 4.8.1
Operating System: Linux 3.1.10-1.9-desktop x86_64
Distribution: "openSUSE 12.1 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:  I was downloading a large 1,5 Gb file and went off and left the machine for an hour.  Came back and it had crashed.  First crash ever with ktorrent, never happened before. Don't know if I can reproduce.  Sent the backtrace. Using KDE 4.8.3, just got updated last night and OpenSUSE 12.1 x86_64 using kernel 3.1.9. Lots of speed variations in the download speed (network problems?)

The crash can be reproduced some of the time.

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