ARGH! Forgot the "delayed staticmethod" line -- in effect I called 
staticmethod twice:

     @staticmethod
     def print_internal_date(filename):
         f = open(filename + 'c', "rb")
         data = f.read(8)
         mtime = struct.unpack("<i", data[4:])
         return time.asctime(time.gmtime(mtime[0]))

     tagdata = {'compiled_fname': lambda x: x + 'c',
                 'size': os.path.getsize,
                 'internal_date': lambda x: 
PYFileInfo.print_internal_date.__get__(x)
             }

     # HERE I BROKE IT
     print_internal_date = staticmethod(print_internal_date)

     def __init__(self, fname=None):
         FileInfo.__init__(self,fname)

     def __setitem__(self, key, value):
         FileInfo.__setitem__(self, key, value)
         if key == 'name' and value:
             self.__get_props(value)

     def testit(self, fname):
         self.print_internal_date(fname+'c')
         PYFileInfo.print_internal_date.__get__(fname+'c')


You're right. It works.
