Comment 5 for bug 532271

@Mathew, it's because the designer was using wrong button order.

@Dmitrijs,
 not here the offending file is still present and the rounded corners are still broken, compare
/usr/share/gconf/defaults/90_light-themes -> maximize,minimize,close:
with
/usr/share/gconf/schemas/metacity.schemas -> ... <default>menu:minimize,maximize,close</default>...

If the correct standard gnome button order is used the theme is wrong. And i havent seen any reason why ubuntu should change button order. It's a really bad thing to do.
