Mailman 3.0 ListArchiverSet.__init__() broken

[NotTheEvilOne]

Hi,

I'm currently developing an alternative archiver for Mailman 3.0 and ran into the following issue:

Jun 21 21:27:13 2014 (23814) Uncaught runner exception: Expected unicode, found <type 'str'>: 'my_archiver_name'
Jun 21 21:27:13 2014 (23814) Traceback (most recent call last):

This may no longer be valid after the port to SQLAlchemy. I'll mark it as such, but if you can still reproduce with current bzr head, please do re-open.
