loads with the shipped Safari, but not with 7.0.6 (9537.78.2, r173946).

(i apologize for not digging deeper)

I tried to reproduce this, and I'm not sure if I'm seeing the same issue.

With either Safari 7.0.3 or Safari 7.1, I get a badly corrupted page (will attach a screenshot). But with a nightly, I get a crash. Is the crash what you are seeing?

For Apple employees: the crash appears to be tracked as <rdar://problem/17969740>

With  7.0.6 (9537.78.2, r174032 (and perhaps the original older nightly I first reported), the page renders IFF the web inspector is displayed.  The page looks like attachment "...eric2.png".

The console holds:

page rendered IFF console is shown during loading

console was displayed during loading, but hidden prior to taking the screen shot.

"A problem repeatedly occurred" is an euphemism for a crash happening every time on page load. It is theoretically possible that WebContent cleanly (yet unexpectedly) exits without crashing, but that's extremely rare, I don't think that I've seen a bug like that before in practice. Can you find any crash logs in Console that would correspond to opening this page?

The fact that this works with Inspector open further reinforces my guess that it's a JavaScript JIT bug - these often go away with Inspector open.

I figured out why this site doesn't work for me - turns out that it breaks when OS X system language is set to Russian (and thus HTTP Accept-Language header field value is "ru"). It is unrelated to this bug.

One other thing, probably not directly related to this bug - I see Safari 7.0.6 on your screenshot. We only intend to support the latest Safari release with nightlies, which is currently 7.1 (or 6.2 on Mountain Lion).

This has been fixed in the past year. <rdar://problem/17969740>
