I have spent quite some time debugging this last night. Line 533 in ZODB.Connection is
state = unpickler.load()
and the message means (it took some time to understand!) that unpickler.load() did not return anything. That appears not to be your problem:
All Python calls return something, maybe "None". Your error message suggests that a "PermissionRole" instance is called without argument. This cannot be caused by a wrong "state" value above. You did read the ZODB3 documentation and the Zope Developper Guide, before you started to do such difficult staff? Dieter
