Moonlight suddenly crashing at start

Describe the bug

Getting a crash in moonlight suddenly: I had to rebuild with ffmpeg 2.8.x this morning, which worked, but I don't think it's really related. See the bt here:

It's worth noting that the same binary, on an identical Arch Linux system, with Intel instead of NVIDIA, works. I suspect this is NVIDIA related.

This should be fixed by 490aa50. Let me know if that works.
