------- Additional Comments from Brady Eidson <beidson at apple.com>
While something deeper might be going on here and warrants further exploration,
this null check certainly fixes the crash.  Other sites in HTMLScriptRunner
null check or ASSERT m_document so it's clearly expected in some situations.
