Description

FFmpeg tool as well as certain applications have problems decoding MP3 files with APE tags.
The tag is reported as an error while decoding stream and some applications using ffmpeg libraries abort decoding in such case.

Issue is also reproducible in ffmpeg 2.7.7 and probably in all releases up to date.

The problematic tag is generated using mp3gain utility but is a valid APEv2 tag.
