Just to clarify: the file nautilus-home.desktop is already built-in Ubuntu (on nautilus package). What I've done is change the *default* LauncherIcon to be nautilus-home.desktop (and not nautilus.desktop).
This means that your current account will not be changed (because nautilus.desktop is in your favorite list). Try to create a new user on your computer and you'll see that the default icon is now the home icon (that opens /home/<user>).
