Allowing the speed to fall below the appropriate Va (tolerance is -0/+5) for the present flap setting and not immediately correcting this.
Of course, this situation is rather theoretical. Flying that slow without any drag out is not really easy when on a glide path; I do doubt that unless one has established that speed in level flight before intercepting the glide, it is even possible to slow down that much without dropping gear and flaps or increasing prop RPM. Also, why would one want to do this unless the flaps are stuck at 0 and one is commited to a flapless landing?
