Function minimization with equality constraints in Mathematica 8

When using constraints with simple equality in Mathematica 8, minimization doesn't work. E.g. FindMinimum[{x^2 + y^2, y == 1}, {x, y}] works ok in Mathematica 6, but gives errors in version 8. Can anyone else confirm (or explain) this? Looks like…

Photo Mosaic in Mathematica: an example from 2008 doesn't work in Mathematica 8

I'm trying to get a Mathematica example working. It's the one on Theo Gray's blog. I think that Mathematica must have changed since he wrote that code (May 2008), since I'm unable to get anything reasonable out of it, despite changing nearly…
