There are known problems with (some) ZClasses when upgrading to
Zope 2.6.1. There are solution for them (--> archive).

I do not know whether your problem belongs to this class.
I miss the "Error Type" and "Error Value" information.
Usually, the know problems reference "'iclass' not found" (or
something similar).
