Upon deploying glance via cs:~openstack-charmers-next/xenial/glance  glance appears to throw a CRIT unhandled error, so far I have experienced this on arm64. Not sure about other archs at this point in time. Decided to bug and will investigate further. 

This occurs when the the shared-db-relation hook fires for mysql:shared-db.
