Bookmarks invisible on public user page

[Former user]

As an unregistered user when I visit the page http://www.bibsonomy.org/user/helfen_in_dd I see the message "bookmarks: No matching items."

Expected: I see a list of all public bookmarks added by this user (all links of this user are set to "visiibility: public"). This still worked some moments ago.
