this is a big PITA for GnomeAboutDialogs, because they auto-destroy
themselves; thus they are single-use only from glade.  i recall discussing
this last year.

another trick, of course, is to use $widget->hide instead of ->destroy.  this
is not possible for the insistently self-destructive GnomeAboutDialog, but
should work for any other.  it also keeps your overhead down, because you're
reusing the widgets rather than recreating them all the time.
