After a quick look, the only thing I could see was that the pins on my board and other boards (see pic on the left from the linux-sunxi wiki on the Pine) are protruding a lot more through the holes, maybe a pin of the connector was bent while placing the part? Or is it just the angle at which the picture was taken that makes your pins look shorter?
