I actually have the "Microsoft Natural Keyboard Pro USB / Microsoft Internet Keyboard Pro", but I suspect that it is the non-square layout that is causing the problem... Switching to generic did indeed solve the problem.
This is with:
Package: gnome-control-center
Source: control-center
Version: 1:2.18.1-0ubuntu2
