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.
