Got a bit further, but then got an Unsouuported URL message:

Since I am able to play the original URL in Firefox, I right-clicked in the video to get its URL. That URL worked fine. In other words, addiing the parameter : "feature=player_detailpage" allows youtube-dl to download the video.

So I tried the original link again, and was told, as expected the video was already downloaded. So I presume something may have changed on the youtube site, allowing the download to work. According, I recommend closing this bug report.
