Upgrade to MM 2.0.13 which, amongst other things, cures this leakage of 
Python 2.x functionality into code that should be Python 1.x compatible or 
upgrade your Python installation to 2.1 or 2.2.

fyi the problem is that various functions from the string module became 
member functions of string objects in Python 2.0 and above. The usage 
causing the problem:

         msg.get('precedence', '').lower

should have been coded as follows to be Python 1.x compatible:

         string.lower(msg.get('precedence', ''))

I believe MM 2.0.13 fixes these glitches that appeared post 2.0.8 if I 
recollect correctly; the one you've stumbled on was not alone.
