MakeCookie/WebAuthent fail when a user changes the password

[Pchamorro]

I just created a new list and I suscribed some users,
but when a user changes his password Mailman shows this
sad message:

Bug in Mailman version 2.1.3

We're sorry, we hit a bug! ....

Traceback:

Traceback (most recent call last):
  File "/var/mailman/scripts/driver", line 87, in run_main
    main()
  File "/var/mailman/Mailman/Cgi/private.py", line 120,

    password, username):
  File "/var/mailman/Mailman/SecurityManager.py", line
219, in WebAuthenticate
    print self.MakeCookie(ac, user)
  File "/var/mailman/Mailman/SecurityManager.py", line
228, in MakeCookie
    raise ValueError
ValueError

I could reproduce this error in other server and with
others lists and users. I was trying under RH 9.0.
Please help me...

Please provide me with a set of instructions that will
reproducibly cause the crash. I am unable to make it happen
in my test set up.
