This is because you have or upgraded to Python 2.5 which issues the
deprecation warning for string exceptions. This warning will be
supressed in Mailman 2.1.10, but it is only a warning. Other than the
log message, nothing has changed.

Which means the subscription is pending confirmation by the user who
has been sent an email requesting confirmation. This in turn is
because Privacy options...->Subscription rules->subscribe_policy is
either 'Confirm' or 'Confirm and approve'

Note that Mailman is not failing. It is doing what it is configured to
do. The only 'error' is the deprecation warning from Python 2.5, and
that is just a warning.
