-- Information about the crash:
- What I was doing when the application crashed:
Just change to enable opengl in desktop effect
using x32 abi. video card is ati hd4200.
I have notice that in /usr/libx32/dri there are no r600_dri.so and swrast_dri.so,so I make a symlink by hand.But it crash kwin.

The crash can be reproduced every time.

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