Does the bathroom ceiling have one of those heater/light/exhaust units that can move air out the bathroom? It may be sending smelly air into the attic or pulling in smelly air from above if the exhaust hose is disconnected and allowing a path for odor. Also, make sure the tub and sink drains have water in the traps so no odors can move thru them. In bathrooms that aren't used often you need to pour some water down the sink and tub drain now and then, the water in the trap evaporates over time.
