Distribution: Ubuntu 12.10

-- Information about the crash:
- What I was doing when the application crashed:

I try to re enable laptops screen which i disabled earlier. I try to do this because when I connect second monitor and disable laptop monitor, some lind for shattered window artifacts appear on the screen. Then I re enable laptop monitor. then crash happens. Then I re disable laptop monitor. Everything works fine. This happens everytime. Now I'm using 4.10. But when I use 4.9.3 still bug exists.

The crash can be reproduced every time.
