backtrace

I've got an apitrace that's causing a segfault in pipe_get_tile_z when the r600g driver is used. The trace can be replayed with llvmpipe without any problems.

I'm not quite sure if this is an apitrace issue, or a driver bug. The application I have traced runs with llvmpipe but is causing a GPU hang with r600g.
