Default VDPAU via libva 1.0.8 crashing

Hi, I'm trying to use VDPAU in VLC, which involves libva. After a Debian update to libva 1.0.8 it crashes, but it used to work with libva 1.0.1.

Program received signal SIGSEGV, Segmentation fault.

From the stack trace, I don't know who's the real culprit here. Whether it's libva doing something nasty, or vdpau calling libx11 the wrong way or libx11 crashing instead of returning an error...

That being said, could the NVDIA devs please take a look at that and decide who is to blame?
