Steps to reproduce:

1. Login with Test Test
2. Deploy the notifications portlet
3. Go to Administration > content > Documents and Media
4. Add Basic Document and subscibe it
5. Add a new user with Administrator privileges;
6. Log out as Test Test and login as the new user;
7. As the new user, edit the Basic Document;
8. Log out as the new user and and login as Test Test;
9. View notification that the Document was edited.
10. Click the notification on the dockbar.

Expected result:
Navigate to the document edited.

Actual result:
On the page shows "The requested resource was not found."

I am not sure it's a bug.
If I add a Documents and Media on one page, it works as expected: navigate to the document.
