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 --

exception: unicode() argument 2 must be string, not None

This was caused by a bug in the email package.  It'll be
fixed in email 2.5.4 and in Mailman 2.1.3.

A better thing to do is to attach a .pck/.db pair of files
for a shunted message.  Then I can run it through my system
and hopefully reproduce the bug.

If the message contains sensitive information or you don't
want to upload it for other reasons, please email them as
attachments to me: barry at python.org.  Make sure you put
"Mailman" in the subject.

ps - moving the various digest.mboxes freed up the blocked lists - 
too many messages with attachments in the digests for me to 
figure out exactly which one was causing the problem, but I'll be 
happy to forward copy of offending mbox to anyone interested.
