[Zope-CMF] object does not support item deletion

[Loren Stafford]

I wanted to try out the CMF for the first time today. So, on NT 4, I made a
fresh installation of Zope 2.3.2b1, verified that it was working, installed
the three CMF 1.0 products in the Products directory, restarted Zope,
verified that the products installed correctly, created a CMF Site in the
root directory (called MorphicsCMF), then tried to navigate directly to the
CMF Site by entering the url http://morphicsweb:8080/MorphicsCMF in the
browser URL box. The CMF Site is, of course, completely empty, but I
expected to see at least the default interfaces for adding members and
content. However, I got nothing but an error. Following is the error and
traceback that resulted.

The error occurs in catalog.py where it is trying to delete sort
specifications from kw. Apparently it's trying to display the list of
current news items, which should be empty, as I haven't added any yet.

Is this a known problem, or did I fail to configure something correctly?
