Livingroom icon not appearing

I was wondering if anyone has had any trouble getting some icons to work in their sitemaps? For instance, the icon I am trying to use is the livingroom one. If you look at the icon set page: the livingroom icon shows up as a question mark. As do a few others. Are these icons no longer supported?


As you can see on that wiki page, the livingroom IS a question mark as an icon - there is no specific image provided in that iconset (yet).

Is there any other icon that appears different from what you see on the linked page? (If that is the case, do you know how to open a network trace within the browser to investigate that?)
