[Hendrik Schreiber]

You can find the sample file at ​http://www.tagtraum.com/download/in.mp3 (as I wasn't able to attach it due to size limitations)

[Carl Eugen Hoyos]

Why do you think there is a bug?

[Hendrik Schreiber]

Because I can read through the file just fine using CoreAudio.

[Elon Musk]

This is because file contains both id3 metadata at start and apetags at end, last one is invalid. Also apetags are invalid as they contain junk data at end.
