Hmmm.....shades of Lufthansa, B747 wasn't it, 2003, where a a plug carrying 115VAC was not sealed, and because it was located in the lower dado area just above the cabin floor, took in air conditioning condensation water, shorted out and started a fire alongside the startled passenger in a window seat in Row 24.
As I recall it, the crew extinguished the fire, ripping away panels to enable them to get to the seat of it.
