juju 1.25.6 + deployer trunk: KeyError: 'series' when declaring series by machine

When running juju-deployer from trunk (revno 195), with openstack-base bundle, or with any bundle exported from juju-gui, I get this key error traceback:

Traceback (most recent call last):

Marking as invalid as we'd do this with native juju bundles now.
