I tried to spawn in an item that vanished from my inventory, but I got this error.

It only started crashing right after I spawned it. I already forgot what the item was, thanks to my short memory... Is there any way to fix this so I can get on my server?
EDIT: I used the wrong file, here is the correct error: http://pastebin.com/3MgacnNv
