Transient OggVorbisHeaderError when setting large values

[GoogleCodeExporter]

For certain Ogg Vorbis files, in the call to save() after setting a large value 
for a tag in the vorbis comments, an OggVorbisHeaderError is raised. Then, 
oddly, the file is left in a state such that calling save() again succeeds.

The traceback (from mutagen svn r108):

Traceback (most recent call last):
  File "t.py", line 9, in <module>
    f.save()
  File "mutagen/mutagen/ogg.py", line 494, in save
    try: self.tags._inject(fileobj)
  File "mutagen/mutagen/oggvorbis.py", line 110, in _inject
    OggPage.replace(fileobj, old_pages, new_pages)
  File "mutagen/mutagen/ogg.py", line 378, in replace
    klass.renumber(fileobj, serial, sequence)
  File "mutagen/mutagen/ogg.py", line 215, in renumber
    try: page = OggPage(fileobj)
  File "mutagen/mutagen/ogg.py", line 87, in __init__
    oggs, "OggS", fileobj.tell() - 27))
mutagen.oggvorbis.OggVorbisHeaderError: read 'TAG\x00', expected 'OggS', at 
0xc689c1

This is a short script that triggers the error:

    import mutagen
    f = mutagen.File('test.ogg')
    big_string = ''.join(['foo']*4096)
    f['arbitrary_key'] = [big_string]
    f.save()

A file that triggers the failure can be found here:

I'm also attaching the first 32kb of the file to this issue.

Since this is hard to debug without reproducing it, closing for now.

Please file again or reopen if you hit this again.
