Mark, To add I think Simon's dataset was too big to go thru 1.3 at a decent time (as I recall think its about 3000 polygons he's dealing with). I think I have run into some of these issues myself in my torture tests but ignored them since they passed regress (I mean all versions failed) and I didn't absolutely verify they weren't invalid, but I'll try to dig some of these up to verify they were invalid.
I suspect its a 1.3 issue as well, but I expect we'll see more of these kinds of things popping up as people will be more able to handle larger geometries and thus will be stress testing PostGIS more.
