Narrative:

Dfw tower, short final runway 17L dfw. I am captain flying. At approximately 400 ft, flight attendant notified us that there appeared to be a fire in the aft galley waste bin. I told the flight attendant to pull the bin out and fire a halon bottle into it. The first officer called the tower and requested crash fire rescue equipment. Just prior to touchdown we were told that we had a false alarm. The first officer told the tower to cancel crash fire rescue equipment. Evaporating dry ice caused the smoke. Supplemental information from acn 428576: the captain asked if there was smoke visible, to which the flight attendant responded yes. Approximately 100 ft AGL the flight attendants told us everything was ok -- it was a false alarm. The flight attendants had mistaken the vapor from sublimating dry ice for smoke from a fire. A pouch of dry ice in the garbage bin was the culprit.
