[Zope-CMF] Upgrading CMF - Problem w/ ZClasses?

[alan runyan]

I went from 1.1 to 1.2b1 by following the instructions (?):

moving out the CMFCore, CMFDefault, CMFTopic, and CMFCalendar (I'm not usin=
g Topics/Calendars) and then unpacking the new 1.2b1 tarballs.  when I re=
start everything *seems* fine on the outside.  but I can not create custo=
m content!

I can create the stock CMFCore objects.  But I have (foolishly?) problems c=
reating ZClass based CMF content.  I get the following error:
