Application: ksysguard (4.5.1 (KDE 4.5.1))
KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-25-generic x86_64
Distribution: Ubuntu 10.10

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

I opened the System Monitor and searched for "transm". The shown list included 2 processes "transmission-deamon" and something like "transmission-da" (I don't remember the exact name). I marked and terminated both of them. 

--> both processes were terminated and after that, the System Monitor crashed

-- Backtrace:
Application: Systemmonitor (ksysguard), signal: Segmentation fault
