This crash is indeed the result of a spear. Its an easy fix. Go into your .minecraft/config/forge.cfg and edit that file. You are looking for the option that says:  You will want to change the false to true and save the file. Then launch minecraft, log in to your world and it will work.

May I ask why you are using such an old version (Beta 17.1) of the mod? If there is some reason you can't update, the error may be a result of using a 1.7.2 mod with 1.7.10 forge. I would recommend you use 1.7.2 forge as well. I would change the true back to false after you have updated or switched to forge 1.7.2.
