Applied. Now Apple needs to fix the QuickTime components so they don't crash
on broken files :)

And as I said several times already: These termination bytes are unnecessary,
because the total size of the parent atom is always known. The more such
redundancies a fileformat has, the more potential security holes you'll have
in the parser.
