id tags in musepack files shown as unknown

I am also affected by this problem. Using 0.3.1b

Same here. The tags of no mpcs are recognized. The Ex Falso tagging plugin shows the tags correctly. While the internal Exaile tag editor shows a standard set of empty tags for Album, Artist, etc. before the set of correct tags that are actually saved in the file. Having this problem with 0.3.1 and with latest trunk.

I think I've found the problem. First of all, Exaile does read the tags as long as the Musepack files are tagged using APEv2 format. However, most of the Musepack files in my collection are actually tagged using ID3 tag and those files are not recognized.

Here is an example using mutagen (the library Exaile is using to read the tags) with python interactive shell:

from mutagen.apev2 import APEv2
audio = APEv2("/mnt/storage/Music/Pink Floyd/The Division Bell/01 - Cluster One.mpc")

This results in a traceback:
KeyError: "'\\xd0\\x07' is not a valid APEv2 key"

Now 2nd try using ID3 instead:
from mutagen.id3 import ID3
audio = ID3("/mnt/storage/Music/Pink Floyd/The Division Bell/01 - Cluster One.mpc")
audio.pprint()

Results in:
u'TDRC=1994\nTIT2=Cluster One\nTBPM=218\nTRCK=1/11\nTPE2=Pink Floyd\nTPE1=Pink Floyd\nTALB=Division Bell\nTCON=Rock'

Now I cleared the tags using EasyTag and retagged them again which wrote the tags in APE format. Now Exaile is correctly adding the files to the collection.

Upen deeper inspection the traceback I got when reading the APE tag from the file is because the data in the APE footer of my files is incorrect. It states that there's e.g 18 tags instead of 17. This means that the mutagen tag parser makes extra iteration and ends up reading footer bytes which causes the "\\xd0\\07 is not a valid APEv2 key" exception.

I have filed a ticket in mutagen regarding this issue:
