+Subject: Settings: Allow directories to be selected (Bug #12832)
+
+Gtk 2.24.31 imported some Gtk3 code that breaks directory
+selection when using a file filter while in directory mode.
+We need to add directories to the filter for the
+GtkFileChooser, otherwise you can't select directories
+while in directory mode...
+Cherry-picked from:
