I suppose catastophic is in the eye of the beholder, but this is very,
very severe to one of our clients. So much so that they may end up going
back to 8.1. The patches to 8.2.5 fix some of the queries, but not all;
some of the problems seem to exist on 8.2.4 as well. We'll try to
develop a self-contained test case that shows the problem, but until then
wanted to give a heads up that a problem may still exist.
