Public bug reported:

In the notifications emitted by the Nova services, the 'publisher_id' fields is sometimes equal to 'None.<node name>' while it is '<service name>.<node name>' (eg, 'conductor.node-1') otherwise. From what I can tell, the "problem" is located in nova/objects/instance.py (see  [1] and [2]).
This isn't a huge issue (eg instances can be created, deleted and so on) but it makes it problematic when trying to rely on this field for external processing/computation.
