Description

Hello,

I have discovered a crash in ffmpeg head, which is r7020 as of this writing,
that occurs every time when playing the attached file.

I have placed the truncated 10mb file in the MPlayer ftp under incoming/r7020_crash/

The file has an invalid header, but still is should not crash. Here's the debug
output :
