Steps to reproduce

1. In addition to the existing superuser, create a second "normal" user.
2. Log in as the normal user
3. Create a new page, click Restrictions --> Edit and select Restrict viewing of this page to Me.
4. Save the new page.
5. Then log in as the administrator.
6. As administrator, the new page can be viewed, its content and the Edit button.
7. Click Tool --> Restriction but nothing happens. (see screenshot: 35x.png)
8. Click Edit, then a page with the title "Not Permitted" appears.
9. The page is even visible in the page tree (see screenshot: tree.png)

For Confluence 3.4.x, the Edit button and the page in page tree are not visible, and the Tool does not show anything (see screenshot: 34x.png)
