[Mailman-Users] Shunting problem

[NFN Smith]

I'm running Mailman 2.1.5 on a Debian 3.1 box.  In the last few days,
I'm getting an increasing number of messages shunted, with error logs
that look like:

> Jan 30 23:10:53 2007 (3315) Uncaught runner exception: decoding

I have no idea why messages might have unicode in them.  

This machine has the following python modules:

  python-central                     0.5.12
  python-minimal                     2.4.4-1
  python2.3                          2.3.5-16
  python2.4                          2.4.4-1
  python2.4-minimal                  2.4.4-1

I'm not aware of any config changes that have been made to this
machine recently.

Two questions:

1) How do I get the shunted messages cleared?  What has to happen
before I run unshunt?

2) What do I need to do to clear the problem that is causing shunting?
