Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.3.1 (KDE 4.3.1) "release 6"
Qt Version: 4.5.3
Operating System: Linux 2.6.31.8-0.1-desktop i686
Distribution: "openSUSE 11.2 (i586)"

What I was doing when the application crashed:
Laptop running OpenSuse 11.2, Linux kernel 2.6.31.8-0.1-desktop.

I'm using ACPI sleeping mode all time.  So system came up normally.  After couple hours using it, mainly reading news on Firefox, Plasma crashed with no reason.
