Hi guys,
Mikel and me are testing some zope3 features in the camp5 sprint in
North Carolina and have seen an strange behaviour on the setindex.
the 'all_of' query performs an intersection of the results got for
each value in the query.
But whe one of the values takes no results, the
'values_to_documents.get(v)' returns None and the
IFBTree.intersection() of 'anytree' with None returns 'anytree'.
We think that should return an empty tree instead. ¿?
Here you have a patch to include this use case in the tests and
another patch to implement this feature:

Thanks, Nando. Yes, this is a good catch.
I have committed tests and fix to the trunk (r73305) and uploaded an
egg to http://download.zope.org/distribution/
(zc.catalog-1.2dev_r73305-py2.4.egg).
I have also committed tests and fix to the 1.1 branch (r73306),
uploaded eggs to PyPI (http://www.python.org/pypi/zc.catalog), and
made a tag (1.1.1).
