    plug-ins: wrap the warning label to something smaller.
    
    As raised on social networks, the big label grows the horizontal size of
    the dialog. Make the label wrappable and give it a smaller wanted size
    (otherwise, just making it wrappable is not enough and the dialog is
    still too big when first appearing, because of how GTK handles such
    widgets :-/).
