No ideas?

I tried to poke at the issue but haven't been able to get any kind of
result.

Some additional points:
* ffplay plays the file without problems with threading
* The issue appears on 32bit/64bit x86 and on PPC as well
* Affects gl, corevideo and png vos (didn't test others)
* Playback randomly crashes in yuv2packedX_MMX2(). I tried to disable mmx
but that doesn't seem to affect libswscale...
