Sup, sup-talk?

Has anyone else had a problem getting their Xapian labels to work correctly
when using Maildir folders from offlineimap?

When I run sup-config and try to add any of my offlineimap maildir folders,
I get the error:

sup-0.12.1/lib/sup/maildir.rb:17:in `initialize': maildir URI cannot have a
host: home (ArgumentError)

I will keep hacking around with it, but any guidance would be greatly
appreciated.

Thank you,

Eric
