Comment 1 for bug 1022237

Yep, the problem here seems to be that we include a pool in the listing even if all floating IPs in it have been deleted

This simple change fixes it for me:

     def floating_ip_get_pools(context):
       session = get_session()
       pools = []
  - for result in session.query(models.FloatingIp.pool).distinct():
  + for result in model_query(context, models.FloatingIp.pool).distinct():
           pools.append({'name': result[0]})
       return pools
