Try drilling through a piece of blue painters tape over the spot next time to see if it helps.
Joe if the problem is the wall crumbling when he tries to drill a hole wouldn't a hammer drill make it worse. And yes to the masonry bit and tape. The only thing I would add is go slow let the drill and bit do the work, don't try to force it because when it breaks thru the back it can break off the plaster keys when those thin pieces of lathe flex or being 100 years old break.
