crashes in glGenTextures( 1, &mTexture ); - what GPU/driver combination do you use? - esp. which mesa version - is it reproducable? - does "LIBGL_ALWAYS_INDIRECT=1 kwin --replace &" fix it?

But it fixed after installing Mesa-nouveau3d package.
Please notice that nouveau 3D/GL support is still more or less experimental, you might encounter other issues. The CSS nvidia driver should do fine (but unless you hit -as i assume?- the ld issue in apprently only OpenSuSE's ld version)
*** Bug 266826 has been marked as a duplicate of this bug. ***
This happens with nvidia as well, i.e. the binary driver.
