Here's something that happens with a file that allegedly has an ID3v2 and an
ID3v1 tag:

 % gst-launch-0.8 -v filesrc location=foo.mp3 ! decodebin ! alsasink

The odd thing is that it doesn't really seem to have an ID3v2 tag, at least not
at the beginning, nor at the end. There's only an ID3v1 tag at the end, and some
lyrics stuff before that.
