You say you have Python 2.6.1, but your Python email library seems to
be python2.5.

Did you upgrade Python after installing Mailman?

It appears your installation may not be completely consistent. What
Python version is invoked by a "python" command.

You may need to rerun Mailman's configure and make install.
