Bug 253817

Application: ktorrent (4.0.3)
KDE Platform Version: 4.5.2 (KDE 4.5.2)
Qt Version: 4.7.0
Operating System: Linux 2.6.34.7-0.3-desktop i686
Distribution: "openSUSE 11.3 (i586)"

-- Information about the crash:
KTorrent started crashing randomly (and often). Similar previuos bug report appeared closed.

The interval between crashes seems to be decreasing - first it was days of KTorrent working perfectly fine, then hours between crashes and now it takes mere few minutes. I can't remember changing any significant system or application settings before crashes started, although I did add and then deleted a couple of RSS feeds in KTorrent. Logging out of KDE and then back in didn't help.

The crash can be reproduced every time.

-- Backtrace:
Application: KTorrent (ktorrent), signal: Bus error
