[Zope] anyone got a foolproof 2.1.6 -> 2.2.0 via import schema?

[Tony McDonald]

I get KeyErrors from 2.2.0 with an Error value of a rubbish character 
when trying to import a folder of various objects. This also happens 
when trying to import the XML version, except the Error Value is 'id' 
(but with no idea of where the error is in the XML file ... 
irritating).

any ideas? this is driving me up the bloody wall.
