KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-22-generic x86_64

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

The USB root hub (Intel HM55) which I used to connect a USB HDD (INITIO controller , WD3200BEVT) suddenly failed. Then KTorrent went crashed.

some dmesg:
