There should be a 'SHUNTING: xxxx.pck' message immediately following the
above traceback. This points to an entry in Mailman' qfiles/shunt/

You can see the message by pointing Mailman's bin/show_qfiles at that
file. There is something bogus and/or non-ascii in that message's From:
header, possibly an RFC 2047 encoded word with the 'wrong' character set.

Please post the message or at least the headers of the message here, and
I will investigate further.
