    src/plugins/nautilus: Fixed crasher when right clicking on background
    
    This was spotted by Debarshi Ray.
    
    There is no action for the background now, unless we decide to tag the
    background at some point, this won't be enabled (for now disabled).
    
    If this code is enabled it won't crash, however, we can only list
    tags, we have no file to apply them to.
