Version:           4.0 (using KDE 4.2.3)
OS:                Linux
Installed from:    Fedora RPMs

Ksysguard crashed while working in background.
I had few applications running (Konqueror, Dolphin, Kmail, amaroK, Skype, Kopete, KWallet, Kmixer, Klipper and KSysguard).
I've closed one tab in Konqueror and started scronling new page then crash occured. I guess, the trigger was CPU usage peak b'cause of fast action and complexity of open www pages (news portal with flash elements, javascripts and such)

My OS: Fedora 11 RC, KDE 4.2.3
Kernel: 2.6.29.3-155.fc11.i686.PAE
Program version: ksysguardd-4.2.3-4.fc11.i586

Here's the backtrace:
