vorbis and flac files with cover art not in library

[Dominik Wild]

Version: 3.2.2

In metadata/ogg.py or metadata/flac.py cover art is stored as binary data using the dict key 'cover'.
In trax/track.py set_raw_tag() each dict value is converted to unicode which obviously fails for binary data.

Traceback (most recent call last):
  File "/usr/lib/exaile/xl/trax/track.py", line 302, in read_tags
    self.set_tag_raw(k, v)
  File "/usr/lib/exaile/xl/trax/track.py", line 406, in set_tag_raw
    for x in values if x not in (None, '')]
  File "/usr/lib/exaile/xl/common.py", line 77, in to_unicode
    return unicode(x)
UnicodeDecodeError: 'utf8' codec can't decode byte 0xff in position 0: invalid start byte

Do you have any (legal) sample flac files that exhibit this problem? I can fix this if I have a sample file.

Should be fixed with r4054.
