Game Crashes loading Character into Uldum

In Development Cataclysm Classic Beta
1

I have a Character that crashes the game as it tries to load in. It is in Uldum. Other characters load fine, though they will also crash if I go into Uldum and turn to look around but I can still reload into them and hearth out. This is the only character that just crashes immediately upon trying to even load.

the logged error is
