You can try to start the nested conversations when you are launching the links (s:link and s:button with propagation="nest"). In seam the breadcrumbs simply display the conversation stack. The repeated entries are appearing because you have started the same nested conversation multiple times by re-entering the same page. To avoid repeating entries make sure you don't have any links that point to the page you are currently using (or use propagation="join" on these links instead of starting a new nested conversation).
