Patch against Catalog.py, from CVS:

*** lib/python/Products/ZCatalog/Catalog.py.original
--- lib/python/Products/ZCatalog/Catalog.py.patched
***************
*** 673,679 ****
                    if (type(so) is type('') and
                        lower(so) in ('reverse', 'descending')):
                        r.reverse()
!                 r=LazyCat(map(lambda i: i[1], r), len(r))

            return r

            return r


I'd use a list comprehension instead of a map(lambda...) if I thought it
would get past Jim ;-)
