Summary: Unexpected MMBadUserError with MM-2.0.11

Initial Comment:
Just upgraded to Mailman 2.0.11. The upgrade itself
worked fine, and basic tests after the upgrade seem to
have worked okay, and mail has been getting delivered.

However I got an email (as administrator) about an
unexpected Mailman error. I have yet to get a complaint
from our users so I do not know exactly what caused the
problem. All I can deduce from the logs is that at
around the same time, someone was
subscribing/unsubscribing via email.

The error message I got by email was:

-----[ START ]-----
An unexpected Mailman error has occurred in
MailCommandHandler.ParseMailCommands().  Here is the

Traceback (most recent call last):
"/usr/lib/mailman/Mailman/MailCommandHandler.py", line
223, in ParseMailCommands
    self.__dispatch[cmd](args, line, msg)
"/usr/lib/mailman/Mailman/MailCommandHandler.py", line
364, in ProcessSetCmd
    self.ConfirmUserPassword(sender, args[2])
  File "/usr/lib/mailman/Mailman/SecurityManager.py",
line 144, in ConfirmUserPassword
    raise Errors.MMBadUserError
-----[ END ]-----

Some more miscellaneous information:

- system is Debian GNU/Linux
- mailman package is mailman-2.0.11-1
- python package is python-2.1.3-3

If anyone has tips as to where to dig for more
information on the cause of this unexpected error,
please do let me know and I will be more than happy to
supply the missing details. It would also help calm my
nerves if I knew whether this was fatal or not. :)

I lowered the priority in a ham-handed approach to
concentrating on MM2.1 bugs.  I simply don't have the time
to continue to support the 2.0 branch for anything other
than critical security problems (which this isn't).  Plus,
you should at least upgrade to 2.0.13, the latest stable
release of the 2.0 branch!  :)

This is very likely fixed in 2.1 as the entire mail command
handler (and so much else :) has been rewritten.

I'm closing this as won't fix.  I recommend upgrading to 2.1.

Hmm.  Looks as if Barry lowered the priority for this with
no comment.  I think that's unfortunate.  I just ran into
this as well.

If this is truly just some user getting their password
wrong, why isn't the exception trapped, and the user allowed
to try again?  This is the reason this puzzles me so:
putting in the wrong password is a common thing to do.  I
myself sometimes trip up the password to my list admin
areas.  So when mailman goes out of its way to send me an
e-mail with such a traceback, it makes me wonder whether
something especially nasty is going on.

A better message would help a lot.  I'd be grateful for some
note on this open issue from the developers, at least.
