Narrative:

We rejected our takeoff below 80 KTS for a 'wheel not turning' light. The light extinguished within a few seconds after the rejection and we taxied back to the gate. Upon arrival at the gate we got a brake overheat light. I informed the ground crew to stay away from the main gear area and confirmed with a ground crewmember that the nose wheel was chocked. After completing the parking checklist I then left the cockpit to talk with arff. Passengers were preparing to deplane because of the potential fire hazard and the first officer was entering the event in the logbook per my instructions when the aircraft insidiously began rolling backwards until the forward entry door contacted the jetbridge. Neither the first officer nor flight attendants said they felt the movement. I don't know if the aircraft pushed the chocks along instead of resting against them or if ramp slope or size of the chocks or some other factor was causal. The aircraft stopped against the jetbridge just as insidiously as it had started rolling. No one was actively deplaning at the time and no one was injured. I directed ground crew to attach a tow bar and pull the jet forward. The passengers were directed to take a seat until the jet was repositioned and then they deplaned uneventfully.

Title: After rejecting a takeoff because of a 'Wheel not turning' warning the flight crew of an MD-80 was further surprised when; at the gate prior to deplaning passengers; the aircraft rolled backwards striking the jetway with an open entry door despite having had the nose wheel chocked by a ground crewman.
