This doesn't help -- in fact, it doesn't even seem to do
what it should do, I get ragged right text like with
GTK_JUSTIFY_LEFT (GTK_JUSTIFY_RIGHT works, though).

A simple test case is atached to this mail.  The question is
how to make the long text fill window width like the
progress bar does.  An ugly workaround is to compute the
right width manually from other widgets and use
gtk_widget_set_size_request().
