ProPhoto Template and CKEditor for WordPress

Bug report.

It seem that if you are using the ProPhoto Template and CKEditor does not
let you insert a Prophoto grid into a page when the editor is active.

To see the template check them out here

I have also asked ProPhoto to work on fixing this in there code. Your
editor is the best out one available.
