While I was able to reproduce this on build 28129, the behavior of the bug was
slightly different:  This time the page loaded, for the most part, but seemed
to be waiting for one more thing.  Then after a few seconds the crash occurred.
 I'm pasting in an updated stack trace for Thread 0 below; please note this
most recent crash occurred in a different method:

Exception Type:  EXC_BAD_ACCESS (SIGBUS)
Exception Codes: KERN_PROTECTION_FAILURE at 0x0000000000000000
Crashed Thread:  0
