I upgraded from Kubuntu 12.04 to 14.04 I get crashes when I want to enter system settings - workspace appearance. When I started audacious I got another crash.
It has something to do with libkdecorations and libQtCore ...

I guess it has something to do with

Sorry for reporting. It appeared I had some conflicting package installed (smaragd). Problem is solved.
