The problem is that you are subclassing SimpleItem.Item and
ObjectManager which are incompatible base classes. SimpleItem.Item
defines its own objectIds method which *always* returns and empty tuple
(because it is not a container). You should be able to safely loose this
base class and all will be right with the world.
