I've been suffering with the same problem. It turned out that I was  
lacking the

versions = versions

line from my buildout.cfg. Sadly, now that I've fixed that bug, my  
application doesn't work any more! :-(
Actually, the application is working fine, but the ZODB has data in it  
which causes the following error:

Traceback (most recent call last):

AttributeError: type object 'IClientIdManager' has no attribute  

I'd like to keep my data; how can I go about getting the ZODB into a  
working state?
