        OS/Version: Linux (All)
            Status: NEW

KWin crashes when trying to activate OpenGL desktop effects.  I do not know if
bug 29181 is related; could be.

I'm on Mesa git master, kernel 2.6.35 using Radeon KMS, xorg-server 1.8.2,
xf86-video-ati git master, Radeon HD4870.

This is the backtrace:

Application: KWin (kwin), signal: Segmentation fault
