I'm running through a Havana install on Ubuntu 12.04 and I am unable to modify users. Most of the keystone commands work, but any command that require modifying the db (such as user-delete or user-role-add) fail with Internal Server Error (HTTP 500).

I'm using MariaDB as the backend. No errors in syslog or query-log.

I do see a lot of rollback queries in the query-log, but I assume that's normal?
