From dolphin to nautilus

[kewlito]

I recently installed kubuntu-desktop-kde4 on my ubuntu installation. Now, the default file manager in gnome is dolphin. Is there any easy way (like with dpkg-reconfigure) to change this? What if later I want to change back to dolphin?

Thanks in advance.

OK, found something that seems to fix it:
In dolphin, I chose "Open With" nautilus, and made that the default action.
Now when I click in places, nautilus opens.

So, the main issue is fixed, but I'm still not sure if that's the proper way to do it. And, what if I want to go back to dolphin as default, how should I proceed?

Thanks.
