I've found this corrupt MPG file that crashes VLC inside
fast_memcpy(). One of the VLC devs took a look at it and
he said that old versions of ffplay also crashes and that
ffplay from SVN HEAD is hanging. Basically, he thought
this was a bug inside "libavcodec".

My original bug report to Ubuntu Launchpad got
marked (probably incorrectly I think) as a
duplicate of a youtube related crash.
