Bug Description

According to the following link plasma-desktop crashes randomly on 64 bit.

http://dilfridge.blogspot.dk/2013/02/kde-4100-plasma-desktop-crashes-and-qt.html

I can't realy tell what I do when it happenens. Basically it realy does not matter, but I guess that messing around with widgets might trigger it.

Debug-packages does not generate any usable backtrace.

Same here after upgrading to Kubuntu 13.04 on all of my Kubuntu PC's (all with 64 bit).

Note, if the CPU is slower, the Desktop crashes more often.

Writing these tree lines, the Desktop crashes on my PC wit Intel Core 2 L7400 1,5 GHz six times !!!
