swift-proxy fails to install when source is a ppa

[Andreas Hasenack]

lp:~charmers/charms/precise/swift-proxy/trunk/

The install hook has this:
def install():
    src = utils.config_get('openstack-origin')
    if src != 'distro':
        openstack.configure_installation_source(src)
    check_call(['apt-get', 'update'])
    rel = openstack.get_os_codename_install_source(src)

    pkgs = swift.determine_packages(rel)
    utils.install(*pkgs)

get_os_codename_install_source() doesn't handle a src that is a ppa, like this: ""ppa:ubuntu-cloud-archive/grizzly-staging". It will just fall off the end and return None. Then pkgs becomes None too, and everything fails:
