Assuming (and I think it's true) that the majority of Ubuntu users' native language is written from left to right, it is also important to notice that both human eyes and screen readers will want to first read the title of a window, and only after see buttons which yield no information at all (since they are the same in all windows).
But then, I feel quite ridicule in commenting about a secret, totalitaristic (and entirely legitimate, sure) decision on the configuration of a project, GNOME, which instead devotes so much attention to usability.
