I have downloaded and installed a new theme before in my fedora machine.
However, I got this warning when I load gvim, nautilus every time.
(gvim:4629): Gtk-WARNING **: Unable to locate theme engine in module_path: "murrine",
(gvim:4629): Gtk-WARNING **: Unable to locate theme engine in module_path: "equinox",
How can I download this theme engine?? and remove this warning?
