Narrative:

Turning to final for the runway at the end of an all night flight; the captain slowed the aircraft to a speed below flaps 5 configuration. He called for flaps 5; however no one had heard him call for flaps 1. At this point a stick shaker occurred and the captain advanced the throttles and the first officer cycles the flaps to 5. During the ensuing discussion about whether the captain had called for flaps 1; the aircraft descended about 400 ft below final approach fix altitude. Both myself and the first officer mentioned the altitude and the captain climbed back to 3;000 ft. No mention made by approach and we landed uneventfully. When finishing a long all-night flight; all cockpit crew members have to be aware of the possibility of fatigue related incidents and be extra vigilant to all flight parameters.
