           Summary: localStorage.key() does not return null for indicies
                    >= localStorage.length
           Product: WebKit
           Version: 420+
          Platform: Macintosh Intel
        OS/Version: Mac OS X 10.5
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: HTML DOM
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: brett at python.org


The W3C Web Storage spec says that for localStorage.key()
(http://dev.w3.org/html5/webstorage/#dom-storage-key) null should be returned
when the value passed in is equal to or greater than what localStorage.length
returns (and the same obviously goes for sessionStorage). But if you do
``localStorage.key(localStorage.length)`` in Safari 4.0.2, instead of getting
null you get ``Error: INDEX_SIZE_ERR: DOM Exception 1``.
