Cannot Read m4b audiobook

[Former user]

For some reason jaudiotagger thinks that my m4b files are videos.

I have traced the problem to this line.

//Level 2-Searching for others "trak" within "moov", if we find any traks containing video
        //then reject it if no track if not video then we allow it because many encoders seem to contain all sorts
        //of stuff that you wouldn't expect in an audio track
        mvhdBuffer.position(endOfFirstTrackInBuffer);
        while(mvhdBuffer.hasRemaining())
        {
            boxHeader = Mp4BoxHeader.seekWithinLevel(mvhdBuffer, Mp4AtomIdentifier.TRAK.getFieldName());
            if (boxHeader != null)
            {
                if(isTrackAtomVideo(ftyp,boxHeader,mvhdBuffer))
                {
                    throw new CannotReadVideoException(ErrorMessage.MP4_FILE_IS_VIDEO.getMsg());
                }
            }
            else
            {
                break;
            }
        }

Whoops, I didn't mean to post this anonymously :P

Commenting the line allows the library to properly load tags. But I doubt that is the correct solution.
