It isn't an MPEG file, it an AVI with MPEG-4 video:

The QuickTime mpeg importer finds a bit pattern that resembles a sequence start code so it scans along for a while looking for an end sequence

Mass closing plug-in bugs, as plug-in support has been removed from WebKit.

Please comment and/or reopen if this still affects WebKit in some way.
