    Frontend-GNOME: use background thread for remoting call in Entry.ProcessKey()
    
    In Entry.ProcessKey() the FrontendManager.NextProtocolManager() call is a
    remoting call. Since Entry.ProcessKey() is executed in the GUI thread we don't
    want to block the GUI and thus do it in a background thread instead.
