After renaming a page with an attachment, there is still a link in the page index to the attachment with the old name. Clicking on the link in the page index does not have sense, it will lead to the creation of a new page.
- create new page "Q new page"
- add attachment "attachment.jpg"
- rename page "Q new page" to ""Q new page new name"
- result : page index contains for letter Q : "Q new page new name, Q new page/attachment.jpg"
