As a workaround, procmail supports negative assertions of that kind:
:0:
* ! ^Subject
no-subject-bitbucket
would do what you want. That may not be acceptable to you, of course,
depending on the facilities available to you, or convenience. Just
throwing it out there, somebody might find it useful.
I don't think it would be hard to add this feature if there's no way
to do it, although Mark may not want to do it in 2.1.x. Wait for Mark
and if he says it can't be done in current Mailman, I'd suggest filing
an RFE at https://launchpad.net/mailman.
