Bug 283406

Application: ktorrent (4.0.5)
KDE Platform Version: 4.6.5 (4.6.5)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-11-generic x86_64
Distribution: Ubuntu 11.04

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

I usually place my torrents data on USB hard drive auto-mounted by KDE Device Notifier. I don't stop ktorrent when I'm sending my laptop to sleep. Sometimes ktorrent crashes after I wake up the laptop.

The crash can be reproduced some of the time.

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