[SOLVED] Atahualpa 3.3.3 and WPG2

I was delighted when I read that 3.3.3 would fix the problems with WPG2 and even happier when someone wrote on the download page that it was working.
I selected Atahualpa as a theme and looked at the preview before activating it. I was able to go to the photo page and it looked fine. (see image 1).
However when I actually activated the theme, although all the other pages looked fine, but the photo page had no formatting at all. (see image 2).
This is quite confusing.
I am using WP 2.7.1 and WPG2 3.0.7
