 Summary of the bug:
 Failing to decode JPEG frames. It happens on a particular JPEG frames
 (example clip and file is attached). Windows preview and IPP have no
 problem decoding the frames. Ffmpeg older versions (a year ago) also
 decoded correcly. But the new version, produce a broken pricture.

 ffmpeg version: 1.1.3
 How to reproduce:
 % ffplay -i Vicon.mkv
 % ffplay -i Vicon.jpg

 Here are part of the error I recieve when running ffplay:
