Summary: Shunt clogged up - RFC2231 unicode problem?

Initial Comment:
Dozens of messages are backed up in my shunt directory 
with the message "TypeError: unicode() argument 2 must 
be string, not None" (full traceback example below).

This seems very similar to a problem fixed by ber with 2.0.x 
earlier this year but I'm running 2.1.2 (on FreeBSD).  I tried 
my best to apply a similar solution to Message.py but 
apparently I don't know enough about python to make it 
work.

Here's a typical Traceback --
