Niche Video Script: double slash in source code

In header.html it says

Code:

---

<link href="{$tpl_base}/style.css" rel="stylesheet" type="text/css" />

---

but that returns this when viewing source code:

Code:

---

<link href="http://mydomain.com/videos//templates/default/style.css" rel="stylesheet" type="text/css" />

---

Notice the double slash before "templates".
