CotF bundle shows a box with text "undefined" if content type description is not set (or not translated?). Expectation is that the popup is not shown in this case.

Context: As we are about to bundle CotF (EZP-26682)) with also the clean install to make sure demo and clean is more consistent, and since the refactoring work in put on hold for now. Given that we should try to solve some of the annoying bugs with the bundle for the LTS version.
