Just creating the /media/$USER directory manually was enough for me, I did not need to chown it.
'/media' is on an ext3 for me
And this system was originally installed with Ubuntu 7.10, and has been upgraded to every version since (so, there might be leftovers like different permissions from that), and was upgraded from 12.04 to 12.10 today, after which the issue showed up.
