Zope 2.9.7 Apparently, I've done something bad and created "cross database reference". At least, that's what I gather from googling the ZODB error. I have 3 filesystem storages. One contains a ZCatalog that references objects in the other. Is this the cause of the error? I can't start zope now - how can I recover from this? 2009-04-13 10:46:24 ERROR ZODB.Connection Couldn't load state for 0x04 Traceback (most recent call last): File "/home/zope/zope_2_9_7/lib/python/ZODB/Connection.py", line 732, in setstate self._setstate(obj) File "/home/zope/zope_2_9_7/lib/python/ZODB/Connection.py", line 786, in _setstate self._reader.setGhostState(obj, p) File "/home/zope/zope_2_9_7/lib/python/ZODB/serialize.py", line 617, in setGhostState obj.__setstate__(state) AttributeError: keys
