Bug in the Smug API

I don't know if this is a bug in the Smugmug API or some sort of data corruption in a gallery. The issue leading to this bug report comes from a Smugmug user using the JFriend HTML5 slideshow.

The API is returning some image URLs for a gallery that do not work. I don't know if they are malformed URLs of if they are just bad objects in the gallery. Here are the details. The gallery is:

http://www.photosbyadamlee.com/Landscapes/Darwin/15626057_3cw28t

The slideshow makes this API request:

/services/api/json/1.3.0/?method=smugmug.images.get&APIKey=m3fjH1x4QjX6N10RsaVUeWr0dgg2oQoZ&AlbumID=9691876&AlbumKey=CAiev&Heavy=true&CustomSize=195x127&Extras=Origin&rnd=1318780258709

Among the data received from the API response is this item:

                    }

The images URLs in that part of the response all return 404 and do not work.

There are two items before that in the response whose image URLs return 200, but don't return any image data. Note: all three of the images that have issues are "Type": "Collected", though there are other collected images in the gallery that do not have issues in case that's a relevant clue.

So, the net result is that we get an API reponse for a list of images in a gallery and three of the images in the response have URLs that do not work. Two return 200, but no image data. One returns 404. This causes the slideshow to "stall" for a short time while these bad images timeout before it finally advances to the next images.
