[Zope] .. cannot be owned by the emergeny user (bug?)

[Oliver Frommel]

another thing that occurred recently .. 
trying to add a python script.
the funny thing is I am _not_ logged in as the emergency user but as a
user I created called "manager", with only the Manager role.

I am running Zope 2.3.0 on Linux 2.2.16

Error Type: EmergencyUserCannotOwn
Error Value: Objects cannot be owned by the emergency user

traceback:
