    background: Ensure that the chooser is tall enough with newer GTK+
    
    We should be pairing gtk_window_get_size with
    gtk_window_set_default_size to avoid inconsistencies between the size
    reading and setting code. eg., in recent GTK+ versions,
    gtk_window_get_size and gtk_widget_set_size_request differ in their
    interpretation of the CSD chrome.
    
    However, gtk_window_set_default_size didn't work with non-resizable
    GtkWindows, until now.
