12.1 - Gnome apps don't work outside of Gnome Shell


I’m using openSUSE 12.1 with XFCE. I can’t get apps like Empathy, Cheese, or Shotwell to run. Empathy and Cheese complain about not being able to initialize Clutter. And Shotwell doesn’t give any descriptive error. Am I missing some sort of Gnome lib necessary to run these apps? They do work outside of Gnome, correct? I am not using a 3D driver, by the way.
