Chest Drop by lua quest faulty

[leek1142 0]

Hey guys.. i want to configure my Chest Drop in a lua script that i found online, but it doesnt really work. I already removed the associated drops and even the entire group from special_item_group.txt. When i click on the chest, my Server just crashes. 

Can anyone say whats wrong and what i have to do to make it working? 

Thanks
