get_os_codename_install_source(config('openstack-origin')) IndexError: list index out of range

I'm raising this bug as I've seen this more than once against glance, but always as an ancillary unit to whatever is under test. There seems to be a race condition of some sort, as a recheck generally works fine.

This case was Trusty-Kilo amulet-full. The install hook fails, but the code path that I see in the traceback hasn't changed in years (!).

What I've not been able to determine from logs is the value of config('openstack-origin') at the time that this occurs.

Logs and artifacts are available here:
