[Germán Poo-Caamaño <gpoo src gnome org>]

commit afb359a69eda470b061e76d4bb82bb64efdd264c

    ev_window: prevent NULL metadata being passed
    
    to ev_metadata_get_int() function inside
    ev_window_get_metadata_sidebar_size().
    
    This could happen if the pdf file returned
    false for ev_is_metadata_supported_for_file()
    
    Fixes issue #1120
