Bug 257314

Application: ktorrent (4.0.3)
KDE Platform Version: 4.5.3 (KDE 4.5.3)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-22-generic x86_64
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed:
I wasn't doing anything - KTorrent wasn't the active window, and hadn't been touched in an hour or so. It was in the middle of downloading from two torrents simultaniously. The crash report showed up while I was doing something unrelated in a browser.
Note that this has happened once before a few days ago, under similar circumstances (non-interactive use, 2 torrents running in the background)

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