Ok.  Does this mean you can reproduce it on command?

What I need to fix this is a way to reproduce it.  If you can do this,
then I need your help.  I would like to see your product, but first I
have to make sure that I *can* debug this using your product.  Your
produce needs to be self contained (not dependent on subclassing python
code I don't have) and must not use any relational database stuff as I
cannot reproduce your database environment.  In other words, if you can
drop your product into a clean Zope out of the box and reproduce this
problem, then you _are_ then man.
