Backtrace from r300 segfault when running mupen64plus.

When starting up the emulator mupen64plus with a ROM, it crashes before loading
the ROM, showing a segfault. Video card is a Mobility Radeon X1700.

Using gdb I traced the segfault back to r300_dri.so
The issues seems to be at line 864 of src/gallium/drivers/r300/r300_emit.c
'buf' is getting set to 0 instead of a proper address.

My backtrace is attached.
