I've honestly never heard of that, but like HighOctane said, it's most likely a short. When you have some spare time, take a quick peek at the wires coming out of the connector for any spots that look burnt, are kinked, or are missing insulation. It might just be a fluke and somehow a wire got pinched or damaged in some way.
Good example, I kept blowing fuses for my interior lighting and no one I spoke to could help lead me to the problem. One day when I had the headliner down to tighten my OnStar antenna, I realized the wires that run to my driver's side sunshade/vanity mirror had somehow rubbed all the way through to layers of insulation and the wire insulation itself. Every once in a while they must have moved just right to touch and would short out, blowing the fuse. I solved it with electrical tape.
