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-default i686
Distribution: "openSUSE 11.2 (i586)"

What I was doing when the application crashed:
Brushing my hand across the Synaptics touchpad generates multiple mouse events.   This causes an overflow somewhere and crashes Plasma.   Not always repeatible but happens frequently.   I haven't tried turning off the Pager or other applets.    Seems to be dependent to the rate and/or quantity of the touchpad events as my touchpad is overly sensitive and can generate a boatload of events given the right gesture and it's exactly this gesture that crashes plasma.

I use the Oxygen theme and have two widget panels.
