This looks similar enough to bug #119224, so I'll be marking this bug as a duplicate of that one. *** This bug has been marked as a duplicate of bug 119224 *** 922070 2 ap 2013-08-28 09:59:45 -0700 It's unclear from the partial stack trace which nightly build you were using. This may not be a duplicate. Could you please re-test with a current nightly, and attach a complete stack trace as a file if this still happens? 922151 3 jon 2013-08-28 12:31:57 -0700 I just re-tested with current nightly (r154730) and I am now able to load http://square.github.io/crossfilter/. FWIW, I was testing WebKit nightly that was current on 2013-08-10 when I filed the bug.
