I tracked this back to some documents which hadn't been changed in a few 
years.

I worked around this by writing a Stepper job to go throguh and 
load/save all the affected document in Zope 2.9 before upgrading, which 
seems to have solved the problems in Zope 2.12.

If anyone's interested, I have a ParsedXML product that works in Zope 
2.12 that I'm happy to release...

cheers,

Chris
