Gnome keeps getting dumber and dumber all the time. First the "Open in Terminal" right click option was gone, now the address bar.
Before at least you had a crayon button to toggle it. Now you need to type / and start typing or Ctrl-L to show it. Makes it a bit harder to copy/paste stuff to it.
Here's how you fix it:
gconftool-2 --type=Boolean --set /apps/nautilus/preferences/always_use_location_entry true
