I guess somehow Zope3 is trying to assign an id to workflow state
definitions too early. I can't "retry" this from my code myself (my
request will simply crash with the trace above), the real fix would
probably to make sure that these definitions can get IKeyReferenced,
but this is beyond my knowledge.

I've tried to explicitly _p_jar.add these objects in the past, but
this fails with recent Zope3 versions.
