Application that crashed: ksysguard
Version of the application: 4.3.2 (KDE 4.3.2)
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.3
Operating System: Linux 2.6.31.12-desktop586-1mnb i686
Distribution: "Mandriva Linux 2010.0"

What I was doing when the application crashed:
System Monitor was open but in background while I was saving text with KWrite. It seemed to crash when I selected the 'Save' option in KWrite menu. I had the Opera browser and the Konsole terminal open at the same time. Opera had a little less than 1 Gigabyte of memory of a 1.5 Gigabyte system memory consumed. Did I crash on a memory limit? Could be... :)
