Application: kwin (4.11.3)
KDE Platform Version: 4.11.3
Qt Version: 4.8.4
Operating System: Linux 3.11.0-14-generic x86_64
Distribution: Ubuntu 13.10

-- Information about the crash:
- What I was doing when the application crashed:
After marked "I have saved my data" field in kwin, I pressed "Re-enable OpenGL detection button" and attached error was generated.
The KDE is running on Ubuntu 13.10 and video adapter is AMD Radeon HD  8670M with 1 GB Dedicated VRAM.
I think I have now the minimum functionalities of video adapter in place. Catalyst Control Center is not working.

The crash can be reproduced every time.
