[Bug 1247827] [NEW] plasma-desktop hang. with kernel callstack

Public bug reported:

I did nothing specifically. Suddenly most things were frozen. I could
still move the mouse and also move windows around but most clicks were
ignored. Clicking on the close-button gave me visual feedback but did
nothing. After switching to tty1 and back, all windows became blank.

This is all the time I start KDE, mostly after starting any application
(like Dolphin or KDE settings).

I recognized that there were some messages in syslog which might be
related. Here with some context:
