[Zope-dev] TypeError: ('argument list must be a tuple') when trying load object from old zodb in Zope 2.12.0a1

Hi All, Any ideas what this means or where it's coming from? Module ZODB.Connection, line 808, in setstate Module ZODB.Connection, line 876, in _setstate Module ZODB.serialize, line 604, in setGhostState Module ZODB.serialize, line 597, in getState TypeError: ('argument list must be a tuple', <class 'Products.ParsedXML.DOM.Core.Document'>, None) cheers, Chris -- Simplistix - Content Management, Zope & Python Consulting - http://www.simplistix.co.uk
