[Zope] Can not add Zope Tutorial with 2.2

[Jochen Knuth]

Hi,

in preparation for the LinuxTag 2000 i tried to add the Zope Tutorial to
Zope 2.2.0b2 (and fresh CVS versions of the last three days) but i get
the following error (i think it's the same error as Oleg mentioned):

Error Type: TypeError
Error Value: ('len() of unsized object', <class Shared.DC.ZRDB.DA.SQL at
85fb7e0>, None)

Traceback (innermost last):

Tutorial was the first action i did.
