Gnome themes uninstalled after update

[Adetque]

Today, I had update manager tell me there was a bunch of stuff to update. So, I updated, and suddenly, all my Gnome themes were uninstalled (http://img10.imageshack.us/img10/2644/screenshotpaj.png), or at least not being noticed by the Appearance Preferences. The question is, how would I reinstall these themes and reset them to default settings?

Also, here (http://filesmelt.com/dl/log.log)'s the dpkg log for today in case it helps.

Thanks in advance.
