What I was doing when the application crashed:
When choosing desktop globe as wallpaper plugin for the first containment, per virtual desktop containments enabled, a progressdialog pops up, stating it will take a few seconds to create some pixmaps - or do some other stuff - cant remember... 
well.. it stood there for some time.. i pressed cancel and plasma crashed..
