Well, I don't think it's a dumb question at all.
I don't currently use Nautilus, but I'm sure there's a drop-down menu in Nautilus that gives a choice for configuring Nautilus. I would look for the address-bar options there. I'll install Nautilus in a moment and experiment and report back success or lack thereof.
A few moments later... Select "Edit" and then "Preferences," and under "Behavior," check "Always use text-entry location bar." That does it! Next time you select a "Place," it will give you a location bar to use. You can also do what UKMadMaN suggested if you don't want to see the location bar every time you select a location.
