Just tried http://roulette.dabase.com/ on r53596 and it also fails to render, while Gecko and Presto can.
I can work around on this problem by adding a timeout. There is some bizaare DOM ready bug I guess.
Both the site and WebKit are at fault here.
The page is using $(document).ready() instead of $(window).load() - $d(document).ready() fires as soon as the DOM is ready instead of waiting for subresources (images in this case) to finish loading.
However, since the image element passed to drawImage() has complete=false, nothing should be done (HTML5 4.8.11), so the exception is thrown in error.
Patch coming in a moment.

Implement correct behavior for drawImage() with incomplete image or video. Autotest included.
For future visitors to this bug, the page at http://roulette.dabase.com/ has now been updated to use $(window).load() :-)
