i fixed this in iemlib's git repository[1]. i'll try to talk thomas into doing a proper release via deken.

Good.
I think is better to use the data-chunk header, cuz broken sound files are far less common than files with metadata.
And broken sound files can be fixed, (copy audio and paste to a new file).
