It should work, though you would see a warning on stderr if the
scrolledwindow already had a child widget (it may only contain one). A
simple test case might make things clearer.

I wonder if this has something to do with the Viewport that gtkmm's
ScrolledWindow::add() automatically adds to ScrolledWindows when needed
by the particular type of child widget.
