This seems to be a problem with an internal mailman process talking to our xmlrpc server (see "PATH_INFO: /mailinglists" in the OOPSes). In this case, the OOPS is valuable, in that it indicates something going wrong in our internal communications.
This means that the bug should go to registry; and that the expat errors in these oopses actually are not noise.
(Thanks to Francis for the diagnosis)
