Description

A Permission Denied exception is raised, if a non-superuser attempts to add a page in a different language.

Steps to reproduce

• Site must be configured to be multi-lingual.
• Log in as a user with permission to add a page.
• That user shall navigate to a page where he page where he has edit permissions.
• In the CMS toolbar, navigate to Language and then to "Add translation…"
• Choose any alternative language.

This raises a Permission Denied exception.

Do you want to help fix this issue?

• Yes, I want to help fix this issue and I will join #workgroup-pr-review on Slack to confirm with the community that a PR is welcome.
• No, I only want to report the issue.

I already found the reason for this and prepared a patch. This error however seems to be a legacy from CMS3 and presumably more cleanup work is required.

This patch fixes the problem in a very hacky way:
