    opensubtitles: Fix error with newer version of PyGObject
    
    We cannot pass an object as user_data, as pygobject stopped handling
    non-integers, non-capsules or not None as possible arguments.
    
    As we do not use Totem.plugin_load_interface()'s signal connection
    feature, pass None instead.
