[Wien] LDA+U+orbital ordering

To continue a recent thread, does anyone have good suggestions about
overcoming probably incorrect orbital ordering in an LDA+U calculation
and/or deciding if it is real? It looks like I've just stumbled into this
one; the GGA & LDA+U charge densities are very different and I think the
LDA+U is trapped in a local minimum with an inappropriate spin state on
some of the atoms (although it could always be real I guess).
