Mailman broken with error loop re digest

[Bug Importer]

Running Mailman 2.03, on BSD Unix.

Mailing list ceased functioning -- mails in queue were not processed, and
logs repeated error
endlessly, resulting in extremely large (5 meg) error log file over a
period of about 8 days. No email
was generated at all during this time -- basically Mailman functioned like
a black hole.

Error Logs showed this:

Initial error message:

Entries in "digest":
> Oct 14 19:51:01 2001 (46261) Fac v 31 - 10768 msgs, 1 recips (0 mime,
1 text,
> 0 disabled)

1 text,
> 0 disabled)

The next-digest and next-digest-topics files were huge. (next-digest was
about 10 megs)

Problem was remedied by deleting all files in qfile and deleting
next-digest and nest-digest-topics
file.

If your header or footer has a bad Python string
interpolation -- e.g. %(no_s_after_paren)

then you will get these errors. This is fixed in the
lastest MM2.0.x release and in MM2.1. You'll still get
entries in your log files when this happens but it won't
break your lists.

I suggest you upgrade to MM2.0.9 (or 2.0.10 when it is
releaed tomorrow).
