    installed: Add proper return value to ::delete-event handler
    
    GtkWidget::delete-event has a boolean return value to indicate whether
    signal emission should continue or be stopped - by avoiding an explicit
    return value, the latter may happen, making the app-folder dialog
    impossible to close.
