The URL provided displays just fine in the regular Safari 3.0.4.
However it does not display properly at all in the latest nightly build (r30053). The image is gone, some text is too.
Sadly I am not good enough to write a pertinent bug report. But I hope pointing this out will help.
The only thing I have noticed is that the anchor tags open at a given line and the href attribute is located on the next line, extending the tag over two lines... is this what causes this erroneous rendering? I don't know. But I sincerely hope you can figure it out. Since this is pretty severe (part of the page is simply missing, I marked this bug as critical; I hope you won't mind).
That article has unescaped <video> and <audio> elements and the nightly is treating content inside them as fallback. From the HTML5 spec:
Content may be provided inside the video element. User agents should not show this content to the user; it is intended for older Web browsers which do not support video, so that legacy video plugins can be tried, or to show text to the users of these older browser informing them of how to access the video contents.
This bug is therefore INVALID, but thanks for taking the time to report it!
