           Summary: Some WavPack files with APE tags fail to play back
           Product: GStreamer
           Version: 0.10.2
          Platform: Other
        OS/Version: All

Please describe the problem:
Some WavPack files fail to play back if they have APE tags, and play back fine
if they aren't tagged. Other files play back fine in either case. I failed to
determine in advance which files would fail or not, but every problematic file
consistently fails to play back every time. Here are samples that you may
download for testing:

http://nufah.free.fr/samples/01-Speak_to_Me-non_tagged.wv
http://nufah.free.fr/samples/01-Speak_to_Me-tagged.wv
http://nufah.free.fr/samples/02-Breathe-non_tagged.wv
http://nufah.free.fr/samples/02-Breathe-tagged.wv

The first three are OK, the last one fails.

Steps to reproduce:
1. Encode a .wav file with wavpack 4.31, make one file with tags and one
without:
$ wavpack -o /tmp/file_without_tags.wv source.wav
$ wavpack -o /tmp/file_with_tags.wv -w "field=value" source.wav

2. play them back:
$ gst-launch playbin uri=file:///tmp/file_without_tags.wv
$ gst-launch playbin uri=file:///tmp/file_with_tags.wv

Actual results:
If the file is problematic, the first one (/tmp/file_without_tags.wv) will play
back correctly, and the second one (/tmp/file_with_tags.wv) will fail:

$ gst-launch playbin uri=file:///tmp/file_without_tags.wv

Expected results:
The files are definitely valid, they should both play back correctly.

Does this happen every time?
Everytime with problematic files. Some files alway play back fine whether they
are tagged or not, I don't know why.

Other information:
All problematic files play back fine with gstreamer 0.8.x. I can't tell whether
the problem lies in WavPack, APE or none of the above specifically.
