This is due to an incompatibility between Mailman 2.1.12 and the email
package in some Python 2.4.x releases. See the March 2009 note in the
FAQ at <http://wiki.list.org/x/pYA9> which includes a link to a patch
to the Python lib/email/Charset.py module to fix this.

I'm surprised that this was the only place you noticed this problem.
Are there occasional shunted messages and error log tracebacks?
