title: Change Gnome preferred applications without installing Gnome?
body: <p>I'm using KDE, but I also use some GTK applications.  When those GTK apps make a call to an external program, they use the preferred applications set for Gnome rather than the ones I've set.</p>
  
  <p>One example is Gimp.  From the Help menu, if I select anything from "GIMP Online" it opens the information in the <em>default</em> web browser.  In KDE, my default web browser is Mozilla Firefox, but GTK applications open Opera.</p>
  
  <p>Installing the <code>gnome-control-center</code> package would probably solve the problem, but that introduces a lot of unnecessary dependencies.</p>
