The package gnome-shell-theme-elementary is out-of-date since October when GNOME 3.2 was released. The current theme doesn't work with gnome-shell >= 3.2.0. The package is mark out-of-date since October 19. I left a message there, but there's no answer. I emailed the maintainer, but I got an error:

So, if possible, orphan the package.
