Backtrace

The game The Witcher (running in Wine) crashes shortly after start:

u_vbuf_mgr_draw_begin+0x198(mgrb=0x7c5937c0, info=0x1c6ec5c,
buffers_updated="À`¬d|", uploader_flushed="")
[/home/sa/Programming/gfx/mesa/mesa/src/gallium/auxiliary/util/u_vbuf_mgr.c:549]
in r300_dri.so (0x01c6e9f4)

This does not happen in 7.10. Bisecting leads to this commit:

I'm attaching a backtrace, but I'm not sure how helpful it is, as getting it
from Wine was quite tricky.
