Errors when running the juju-gui charm tests via juju-test

There were errors when using the juju-test command to run the juju-gui charm tests, output below. Revno 59 of lp:~juju-gui/charms/precise/juju-gui/trunk

Also, JUJU_ENV was not set, and -e was needed, because juju-test does not use the default environment by default.
