GetPlayerMapPosition broken in 4.1

it seems GetPlayerMapPosition() returns 0,0 for anything other then player, this results in map not displaying party members, only self, as well as any addons using it also not to work, such as range finders. Seems like a shortsighted break, or intentional one aimed at boss mods using it for complex range finders or arrow functions. But I'm hoping it's not latter. I'd hope blizz would add their own range finder before breaking mods that do it, especially since so many encounters are designed around the assumption of having one.
