I'd check into that, yeah. There's a possibility that it's just capacitively coupled, which is unlikely to be a problem. Also could be weird building wiring, which happens more often than you'd think. Or it could be weak insulation somewhere, though that's less likely. In any case I wouldn't be too worried. Maybe check it out with a few different receptacles and consider getting a receptacle tester if that turns up something interesting. I kind of hate Apple, but their chargers set the benchmark for the industry. I doubt they're your problem.
