It probably isn't an issue. I'm just guessing with incomplete
information.

This specific error has nothing to do with bounce processing. It would
have resulted in a "we hit a bug" message when someone tried to
unsubscribe from the options login page for some list. It indicates
that that list's lists/LISTNAME/pending.pck file is corrupt. This
could also cause errors in bounce processing for that list which
should also be logged.

Try the following for each list (assuming normal RedHat paths)

#! /bin/sh
for list in `/usr/lib/mailman/bin/list_lists --bare`; do
  echo $list
  /usr/lib/mailman/bin/dumpdb /var/lib/mailman/lists/$list/pending.pck
done

If the attempt to dump the pending.pck for a list throws an exception
with a traceback, rather than dumping the contents, that list's
pending.pck is corrupt. Remove it, and a new one will be created when
needed. This may fix bounce processing for any list with a corrupt
pending.pck.

Also note the following:

The bounce log messages like:

Sep 25 18:43:55 2009 (5775) test: city at domain.gr already scored a
bounce for date 25-Sep-2009

are normal. Once a bounce is recorded for a particular user on a
particular list, all subsequent bounces for that user/list on the same
calendar day are ignored. This also means that if the threshold is,
e.g., 5 and the user's score is 2 (from a bounce on this day),
lowering the threshold to 2 or less will; have no effect for that user
until a bounce is received on a subsequent day.
