Bug 275928

Application: ktorrent (4.2dev)
KDE Platform Version: 4.6.3 (4.6.3)
Qt Version: 4.7.2
Operating System: Linux 2.6.35.13-92.fc14.i686 i686
Distribution: "Fedora release 14 (Laughlin)"

-- Information about the crash:
This crash doesn't happen immediately but does so after several hours of operation. 

The valgrind seems to run and then get stuck or is it ktorrent that gets stuck? Several popups appear, then NOTHING.

This version of ktorrent is:
ktorrent --version
Qt: 4.7.2
KDE Development Platform: 4.6.3 (4.6.3)
KTorrent: 4.2dev

The crash can be reproduced every time.

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