I've seen this error posted before - but can't recall the details -
almost certain it's a bug.  Check the collector - and/or install Zope 3.3.1

Zope3 and Zope2 are different beasts.

The Zope3 'home' page is http://wiki.zope.org/zope3/FrontPage
There's a Zope3 FAQ at http://wiki.zope.org/zope3/FAQ

I recommend the book 'Web Component Development with Zope3'.
The 2nd edition has just been released.  Seriously consider getting it.

The author's website is http://worldcookery.com/ and the 'Appetizers'
section lists refs to tutorials and getting started with zope3.

Unless you need to specifically use Zope2 for some legacy purpose, USE
Zope3.  You'll be a much better programmer.
