crash in plasma desktop shell: QGraphicsScenePrivate::processDirtyItemsRecursive

[Stefan Fleiter]

Binary package hint: kdebase-workspace

Plasma crashed again on me.
I did not do something special at the very moment.

I installed the missing dbg packages to improve the stracktrace information,
I hope this helps.

Application: Plasma-Arbeitsfläche (kdeinit4), signal: Segmentation fault
