This problem has been 'partially avoided' since Mailman 2.1.7 and fixed
since 2.1.9. See the thread that starts at
<http://mail.python.org/pipermail/mailman-users/2007-August/058021.html>
for a fairly complete description of the issue and see the post at
<http://mail.python.org/pipermail/mailman-users/2007-July/057768.html>
for information on what how to edit this list's digest.mbox file to
clear this problem (until the next time). After editing the
digest.mbox, you can run bin/unshunt to finish processing the shunted
messages, but before doing this, it is a good idea to run
bin/show_qfiles on qfile/shunt/* and delete any messages you don't
want.
