period task error: (ProgrammingError) (1146, "Table 'heat.watch_rule' doesn't exist")

On a clean install of devstack + heat I get:

2012-11-19 11:09:38 WARNING [heat.engine.service] periodic_task db error (watch rule removed?) (ProgrammingError) (1146, "Table 'heat.watch_rule' doesn't exist") 'SELECT watch_rule.created_at AS watch_rule_created_at, watch_rule.updated_at AS watch_rule_updated_at, watch_rule.id AS watch_rule_id, watch_rule.name AS watch_rule_name, watch_rule.rule AS watch_rule_rule, watch_rule.state AS watch_rule_state, watch_rule.stack_name AS watch_rule_stack_name, watch_rule.last_evaluated AS watch_rule_last_evaluated \nFROM watch_rule' ()
