vm fault report

Running mplayer with -vo gl:yuv=x  with x>1 causes GPU VM fault.
yuv=0 is software rendering, that works fine.
yuv=1 uses GL_NV_register_combiners and that doesn't fault but the output is
unusable.

The other values use fragment shaders, those are all broken.

Reportedly the apitrace works with older versions, mesa 11.2.2 and llvm 3.6.2.
