Okay, here is the story. I measured it and between the housing and ground in the wallsocket is: 0.5-0.9VAC and 0VDC. I think it's just some noise coming from inside the power supply somewhere. Maybe some people with 110VAC can feel it as well if they are real sensitive. But with 230VAC you will feel it probably better. Cheap switched power supplies are known for putting some noise on the DC side also known in that world as "ripple voltage". So it's probably cheap. :P
