exceptions.UnboundLocalError: local variable 'settings' referenced before assignment

[Evan]

I'm running into the following with the latest version of juju (0.6.0.1+bzr607-0juju2~precise1):

Looks to be a regression from r607, changes from the following merge proposal:

looks like this effects primarily subordinate deploys, which weren't in the functional test case, adding some unit tests.
