        - Fixed <rdar://problem/4631837> REGRESSION: Reproducible crash on
        FCKeditor demo (9911)

        * WebCore.xcodeproj/project.pbxproj:
        * bindings/js/kjs_html.cpp:
        (KJS::JSHTMLDocument::putValueProperty): Check for a null body element before
        forwarding the put request to it. I confirmed that no other parts of the
        file use 'body' or 'bodyElement' without checking for null.

        Also, use 'body' rather than 'bodyElement' because dir can bet set on
        any element, not just HTMLBodyElement.
