    Bug 798063 - Crash when opening SX Editor
    
    Scheduled transactions place register pages in embedded windows
    and their priv struct is different so treating one as a main window
    crashes. Besides, the register in the SX editor would never be
    read-only. Make sure we have a GncMainWindow at the beginning of
    main_window_update_page_set_read_only_icon.
