Cannot create a new page from Pages > Add a New Page if Languages/Localization is enabled

Description

This Issue is a follow up to (and my copy of it DNN-10722)

Problem: In a multi language environment adding pages does not always work.
Reproduction:
1) Create a DNN environment with TWO Languages (eg. EN / FR)
2) Create a parent page in two languages (eg. EN / FR)
3) Create a Child Page with two languages (EN / FR)
4) Now ADD a third Language to the portal (eg. DE) with "Add missing languages" - Button
5) go to the CHILD page and try to add missing language --> Page reloads, language is not added, error as in

Workaround / Fix:
After above Step 4:
4a) Go to PARENT Page, edit localisation and add missing translation
5) go to the CHILD page, edit localisation and add missing translation
6) CHILD Page is successfully created in 3rd language
