[Zope] Upgrading from 2.5.1 to 2.6.0 Problems

Hi Sascha,

thanks for your reply. It solved part of the problem.

It works for the three Zclasses that Zope didn't import
before. I'm not having that long error message about the
"pickled data" anymore, but I'm still having this one:

What could be the problem?

Thanks in advanced,
