Clicking profile link for deleted user takes me to my own profile page

Issue
Clicking on a deleted user´s name/link (e.g. in the document details page) forwards me to my own profile page.

Steps to reproduce

1. Search for any document that was modified by a user which was deleted in the meanwhile. For example I found a document modified by brobinson (deleted user)
2. Open that document´s document details page.
3. One can see brobinson as the user who modified it last. Note, in that view the (deleted user) suffix is not displayed.
4. Click on the deleted user´s name to open the related user profile.

Current behaviour
Clicking on the name of a deleted user forwards to the own user profile page.

Expected Behaviour
Either the username should not be clickable if the user was deleted or a stub profile should be displayed.
