Steps to reproduce:

1) Clean install of 6.2 Beta 6.2
2) Create a new product "zoo" with repo "myzoo" pointing at https://repos.fedorapeople.org/repos/pulp/pulp/demo_repos/zoo/
3) Sync the repo, and go back to the repo info page. The Published at will be:

http://$SERVER/pulp/repos/Default_Organization/Library/custom/zoo/myzoo

(note, no trailing slash)
4) If I copy/paste that value into a browser, the links on the page will not work since the page is source is

<li><a href="cat-1.0-1.noarch.rpm">cat-1.0-1.noarch.rpm</a></li>

I believe the correct logic is to change the code which generates the ul to use ./ in front of the name. However, apepnding a "/" to the PublishedAt may also work.
