Public bug reported:

When a delete is issued for an instance that doesn't have a cell_name in
the db, a delete is broadcast to all cells. As that message passes
through the cells rpc layer the instance is converted from an object to
a dict. This causes a problem when it gets to the cell since the delete
methods expect to receive an object.
