Public bookmarks not on Profile page?

I'm not managing to get the public bookmarks visible on a profile page.
The bookmarks can be markt as public.

Permissions set for authenticated user:
bookmarks module
-administer bookmarks
-administer own bookmarks v

bookmarks_public module
-create public bookmarks v
-view public bookmarks v

I'm using content profiles. Has that anything to do with this problem

Thanks, Wims
