[Zope3-Users] Strange ZODB error

[Gary Poster]

You probably need to find out what the object is for anyone to have a  
chance of helping.

I usually just put a pdb in the ZODB that is triggered if there's an  
error here, and then start poking around.  Using the postmortem debug  
publisher might work too, but it has caused enough problems for me in  
the past that I dropped it, myself.
