Backtrace log

Hello,
I use GIT versions of Nouveau and Gallium 3D driver. I'm getting
reproducible
crash of stable Compiz 0.8.6 while starting some applications in maximized
mode, e.g Gedit, Geany, Komodo Edit. Backtrace and patch (I'm not sure if
it's
a proper fix) included.

On 2 my NV40s (NV43 and NV4B) compiz segfaults on the same place when using
"resize"(normal mode) and "switcher" plugins.
dri2_process_buffers is trying to
process even if buffers were not allocated.

With this patch compiz does not segfault, but decoration flickers while
resizing window - white border is shown instead. Anyway it reduces the problem
to flickering and lack of textures instead of crash.

I guess this was fixed in the meantime?
By looking at the backtrace it doesn't seem to be Nouveau issue -
reassigning
to "Mesa core".
