backtrace

Since yesterday night, I've been unable to get a window manage running (see
attached backtrace). After bisecting Mesa (was the only thing recompiled), I
found out that the following commit was the culprit. Any application being
launched while bisecting from and after that commit ends up with a
"r600_texture.c:562: r600_texture_get_htile_size: Assertion `0' failed" error.
