Server closes when someone joins. I think it's a glitched chunk but I don't know how to fix it. Console crash log - http://pastebin.com/fhzGVucS

Somebody told me to delete/fix the userlist. How do I do that? What is the file name? Console log - http://pastebin.com/j0dPgJxs

Care to explain how to do that?
