Description Dustin Falgout 2013-03-05 03:43:39 UTC
Application: kwin (4.10.00)
KDE Platform Version: 4.10.00
Qt Version: 4.8.3
Operating System: Linux 3.5.0-25-generic x86_64
Distribution: Linux Mint 14 Nadia

-- Information about the crash:
- What I was doing when the application crashed:
Went into settings, selected a new window decorartion theme and clicked apply. Does not matter what decoration I choose. It happens everytime. All of the windows are functional just without a border or title bar. Sometimes using "kwin --replace" will correct the issue while sometimes logging out is the only way to fix it.

The crash can be reproduced every time.

-- Backtrace:
Application: KWin (kwin), signal: Segmentation fault

I seen this requested on another report that was thought to be different issue than this one, so I thought I would include: 

Comment 2 Dustin Falgout 2013-03-05 04:18:44 UTC
Also not sure if this is helpful, but after changing my QT Graphics System to "Native" & leaving OpenGL, the kwin crash cannot be reproduced.
