H264 decoding error messages from a possibly valid mxf file

Description

http://thread.gmane.org/gmane.comp.video.ffmpeg.user/51662

A user uploaded a mxf h264 sample that shows different error messages on decoding. The last message is shown several seconds before EOF, so this is at least not a problem related to bad cutting.
