Description

Steps to reproduce:

Create a Page 'A'
Create a page 'B', where the content is a redirect to 'A'
Try to move 'A' to 'B'

Expected behaviour: Be able to overwrite the redirect, at least as admin by deleting the page on the move special page.

Current behaviour: You get an internal error:
