commit 37a4c09145604a056f48f7484fe87e7d247a7af9
Author: Mark Page <aptit...@btconnect.com>
Date:   Wed Nov 8 15:23:35 2017 +0000

    Prevent GTK assertion with FilePicker dialog
    
    If "use-header-bar" property of the dialog is set to TRUE,
    it uses a GtkHeaderBar for action buttons instead of the
    action area.
