While waiting on the ramp after landing, the flight crew started the airplane's auxiliary power unit (APU) and about 30 seconds later, the cabin began to fill with smoke. The captain ordered an emergency evacuation utilizing the airplane's four evacuation slides. All slides functioned normally; however, during the egress a passenger sustained a fractured bone in her right foot. Examination of the airplane revealed a broken hydraulic line, which allowed hydraulic fluid to accumulate in the area of the APU inlet.
