Summary: Scrubber broken on bad base64 messages

Initial Comment:
This is a stupid virus email that got thru to one of
our lists. I'm happy to remove it from the archive, but
I'm guessing if this was sent to a list again, it would
cause the same error in the delivery and not just in
the archiver.

Pickling archive state into
