Comment 3 for bug 147836

I incorporated a bzr status into our `make lint` to report on the changes from the parent branch. Developers who branched from /rocketfuel/launchpad/devel get this same error, but I note that when the protocol is switched from bzr+ssh to sftp, it works fine.

bzr status --short -r ancestor:bzr+ssh://<hidden>/rocketfuel/launchpad/devel
bzr: ERROR: exceptions.AttributeError: 'RemoteRepository' object has no attribute '_make_parents_provider'
