Game crash bug

While looking at a sword called Krol Cleaver, and while still looking at it and then pressing the C key to look at your character items equipped it crashes.

(Edit) After further inspection i notice that it happens when ever you have your bag open and click c.
(Another edit) Upon even further inspection i noticed that it happens every time i hit c.
(Third edit) I cant even open up the character window because my game crashes.. Im confused

You have to go to the taxi npc (Troll shaman with guitar) and click "fix C error" and follow the instructions.
