Comment 2 for bug 1119671

could either of you add the output of juju deploy -v which includes the traceback. Can you confirm that you have juju-origin: ppa specified for the maas environment?

The suggested fix in #1 doesn't pass the unit tests. I'm having trouble reproducing this error in unit tests and i wonder if the issue is related to a version mismatch (hence the juju-origin_ question).
