Fedora 18 - System Settings are suddenly not initializing

view story

http://forums.fedoraforum.org – Hi all, To note: I'm on Gnome 3.6.3 running Fedora 18 My 'System Settings' is not initializing. Such as, when I try to access the program through the drop-down menu on the panel or the icon in the app drawer. It was working at least a day ago; I don't understand what's going on here. The package "Gnome-Control-Center" is installed, and I can access System Settings via terminal. But I'd like the normal way to start Settings back. I don't know what other information I can provide here. If you need something more, I'd be happy to get it for you. :confused: (HowTos)
