[Zope] POSKeyError nightmare

[Kevin Carlson]

Dieter,

I'm not sure I understand what you mean by fixing them all as shown 
above.  You mention loading the object from the ZODB and deleting the 
broken references, but I'm not sure how to do that.  I have looked 
around for info on loading objects by oid but cannot find anything 
helpful.  Can you help me out?

Thanks,

Kevin
