gtk3: FileChooser schema not found

[Allin Cottrell <cottrell wfu edu>]

I have glib 2.28.0 installed, along with gtk 2.24.0 and gtk 3.0.0.
Calls to the FileChooser in my app work as expected in 2.24, but
in 3.0.0 they produce:

GLib-GIO-ERROR **: Settings schema 'org.gtk.Settings.FileChooser'
is not installed

and the program aborts. The file
org.gtk.Settings.FileChooser.gschema.xml is installed in
$prefix/share/glib-2.0/schemas (2133 bytes).
