The original question is really about stalling with yaw on.
I once witnessed a glider incident that demonstrated what can happen rather neatly.. The glider was returning to land but had got slightly low. There was a modest crosswind and he was crabing to track the runway centerline. He also appeared to be flying slowly trying to "stretch the glide". He made it over the grass strip ok but when he kicked the rudder to remove the crab the downwind wing stalled (or lost lift anyway) and dumped him in from about 10 foot up. Fortunately he was ok.
