Log message:
        fixed problem with Expose and destroyed handle.
        In some cases it could be, that Expose was called but the handle already
        was destroyed.
        The X events are queued if the app does a lot of work and the events 
then
        gets to the Widget classes. but if the app destroyes a window and after 
that 
        the events gets processes we get "the widget was destroyed" exception.
        This fix, checks the if handle is not null and then calls OnPaint.
