Still occurring on nightly r45585.

Brought up XCode to see if anything was obviously wrong.  But I'm lost,
wandering in a sea of C++ wonderfulness.  :-)

Here's where things appear to be breaking down.

On the stack, I'm in JSDOMWindowCustom.h, in
JSDOMWindowBase::allowAccessFromPrivate, which looks like this:

----
ALWAYS_INLINE bool JSDOMWindowBase::allowsAccessFromPrivate(const
JSGlobalObject* other) const
{
    const JSDOMWindow* originWindow = asJSDOMWindow(other);
    const JSDOMWindow* targetWindow = d()->shell->window();

    if (originWindow == targetWindow)
        return true;

    const SecurityOrigin* originSecurityOrigin =
originWindow->impl()->securityOrigin();
    const SecurityOrigin* targetSecurityOrigin =
targetWindow->impl()->securityOrigin();

    return originSecurityOrigin->canAccess(targetSecurityOrigin);
}
----

When the return statement is processed, originSecurityOrigin is null.  Can't
really decipher the origin/targetWindows to tell what's going on.  

An obvious tidbit after perusing the source is that ScriptFunctionCall on the
stack at 10 appears to be calling a function "inspectedWindowCleared".
