Description kingdergrosse 2011-02-14 20:12:55 UTC
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

Do you have NVidia?  If so, do you know what version of drivers?
Comment 2 John Tapsell 2011-03-20 22:58:05 UTC
Looks similar to
Comment 3 Christoph Feck 2011-03-21 03:23:49 UTC
I don't know which bug you had in mind, but this doesn't look nvidia related.
Comment 4 John Tapsell 2011-03-21 09:32:39 UTC
I know that it doesn't seem that way - but could you answer my question anyway please?
Comment 5 kingdergrosse 2011-03-30 03:29:34 UTC
Sorry, I had no access to my mails during the last 2 weeks...

I'm using a AMD graphic card and the fglrx driver.
Comment 6 John Tapsell 2011-03-30 12:00:26 UTC
Fixed in KDE 4.6.2 and 4.7
