Crash on turn in of Ghost Hunt quest

[betawind]

Every time I try to turn in the quest the game crashes with the following error:

Version: 1.03c Steamy Hot Stable

Error: System.NullReferenceException: Object reference not set to an instance of an object.

I'm currently unable to continue past this point.
