[Zope] Plone in debian unstable

[Michele Bendazzoli]

A few days ago i have successfully installed plone site an play around
with it. This morning i have upgrade the default version of python from
2.2 to 2.3 and selected/deselected some package.

Now when i try to access to the plone selecting it and clicking the view
tab, the following site error message was displayed:

***
Site Error
An error was encountered while publishing this resource. 

AttributeError

Sorry, a site error occurred.

Traceback (innermost last):

Can someone point out me in the right direction? Is this a conflict
between zope and the 2.3 version of python or i have made some mistake
that I'm not aware of?

Thanks in advance for any advice
