graph.facebook.com/username has stopped working. There is an unpleasant workaround. In my limited testing, this works in Chrome.

Wherever you see the facebook user name in a timeline entry, right click and select "inspect element." In the window that opens, scroll up a little and look for the string:

"data-hovercard="/ajax/hovercard/hovercard.php?id=".

The Facebook id of the username you right clicked on follows the = sign.

This only seems to work on names on the timeline.

Facebook – Getting the “real” Facebook profile picture URL from graph API

The first URL gives a HTTP 302 (temporary redirect) to the second. So, to find the second URL programatically, you could issue a HTTP request for the first URL and get the Location header of the response.

That said, don't rely on the second URL being pemanent. Reading a little in to the HTTP response code (of 302 as opposed to a permanent 301), it is possible Facebook changes those URLs on a regular basis to prevent people from—for example—using their servers to host images.

Edit: Notice that the CDN URL the OP posted is now a 404, so we know that we cannot rely on the URL being long-lived. Also, if you're linking to the Graph API from an <img> on a SSL-secured page, ~~there's a parameter you have to add~~ make sure you use https://graph.facebook.com.

Update: The API has added a parameter – redirect=false – which causes JSON to be returned rather than a redirect. The retruned JSON includes the CDN URL:

{
   "data": {
      "url": "http://profile.ak.fbcdn.net/...",
      "is_silhouette": false
   }
}

Again, I wouldn't rely on this CDN URL being long-lived. The JSON response is sent with permissive CORS headers, so you're free to do this client-side with XHR requests.
