Just did an svn up to Revision: 643, but I'm still getting an unmatched
checksum error from gtkpod.

This is what it shows in the gpodder console:

[42270.381] (iPodDevice) Error when writing iTunesDB.ext
Traceback (most recent call last):

    return os.stat(filename).st_size
TypeError: coercing to Unicode: need string or buffer, NoneType found

Googling that last bit got me this:

"This may be an indication that in your database you have a record with a
None value, e. g.

        [('Developmental Neurobiology', 'ANAT2008'),
         ('Neuroanatomy', 'ANAT2009'),
         ('Man in black', None)])

and most likely the right fix is to correct the database entry and make sure
that no new such records can be entered into it."

However, I have no idea how I would go about following this advice...

 Fry: I've only got two fantasies left: to be invisible in a 
chocolate factory, and to be romantically linked to a  celebrity.
 Bender: I could pound your head 'til you think that's what happened.
 Fry: Okay.
