Ok, so this thread is quite old, but just to let you know, I found the problem with this little glitch, and the solution to it too. http://fallout.wikia.com/wiki/Crush_the_White_Legs Bugs section, last entry: Sometimes, after the rock detonation and Joshua leaves you to move on ahead, he leaves you his entire inventory, including his Companion Ammo, Magical. When this happens, at the end of the trail, there will be a scene where Joshua will kill some White-Legs and confront Salt-Upon-Wounds, but he won't actually do anything because he has no ammo. In order to continue this scene, you need to use the console on him and "additem 00176e54 1".
