There's a good chance that this is fixed with:

http://cgit.freedesktop.org/mesa/mesa/commit/?id=8975f83402e3f5915f3f1a27599c24d908b7706d

Of course note that vdpau still won't work for pre-nv84 cards, but it
shouldn't
crash quite like this. (It'll probably crash in a different way, as
decode_bitstream isn't set. I did try to get it to work, but in the end, the
actual decoding didn't work correctly.) More information on what ought to
work
is at http://nouveau.freedesktop.org/wiki/VideoAcceleration/
