The idea is to phase our our current gnome-font-selector and just
use the one in Gtk, as the author has promised to adapt the
GtkFontSelector to fit the gnome needs as well.

I do not understand the argument here.  Can you show us a detailed
example of why we should use a GtkFrame as the base widget?

I do not like this approach.  An interface that shows me lots of fonts
and the complains about not being able to use one is pretty bad.  I
like more the idea of the filter which was suggested by the
GtkFontSelector author: You pass a number of criteria about the fonts
that can be shown and only those are shown.

I like Martin's proposal (ie, subclass the Gtk file selection).
