+gnome-desktop contains the libgnome-desktop library as well as a data

-The %{name} package contains an internal library
-(libgnomedesktop) used to implement some portions of the GNOME
-desktop, and also some data files and other shared components of the
-GNOME user environment.
+The libgnome-desktop library provides API shared by several applications
+on the desktop, but that cannot live in the platform for various
+reasons. There is no API or ABI guarantee, although we are doing our
+best to provide stability. Documentation for the API is available with
+gtk-doc.
