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).
