Description Edward Sabol 2010-09-27 19:48:53 PDT
When visiting http://trailers.apple.com/trailers/paramount/truegrit/ with the latest Webkit Nightly (r68419), I noticed that the "Info" button and the "Watch Now" menu did not render. The Error console reports:

"TypeError: Result of expression 'arguments' [undefined] is not an object" in /trailers/global/scripts/lib/scriptaculous.js:97

No such error occurs when you use r68419 on Intel. (Both 10.5.8 and 10.6.x were tested with extensions turned off.) I tested the previous nightly build (r68242) on PowerPC and no error there either, so the regression must have occurred between r68243 and r68419. I can't really narrow it down any further than that.

Using git-bisect, I tracked this down to r68338.  (Building the Interpreter for x86_64 causes a crash when loading the same page.)

Here's another page with the same issue from my Bug 46916.
