From an email:

I have only one small request. Can you make the link not a relative path?

When I am at the Hudson main page, the "Shelved Projects" link works great.

When I am at "My Views"(http://${hudson}/me/my-views/view/All/), the target is effectively "http://${hudson}/user/${user_name}/my-views/view/All/shelvedProjects", which if you try to go there, you get the very lovely "Status Code: 404".
