NullRefrenceException upon login

[Slayeh]

When i log in with one of my characters, i get a null refrence exception:

Edit: I just worked it out - its not the char - its Malas (where that char spends almost all of its time) If it makes any difference I'm playing on Imagine Nation 2 (RunUO rc0), and i think it uses a std Malas map
