For a general answer... I have zero concerns about two (or even three) links to the same URL on a single page of my website. I place links when it makes editorial sense and when it is helpful to my visitors.
Although I have not heard any specific information about how google handles duplicate links on a page I doubt that they find a problem with it. Why should they? In my opinion, linking to the same URL two or three times on a page can be a signal of its importance.
