           Summary: WebArchiver - attempt to insert nil exception when
                    archive empty iframe
           Product: WebKit
           Version: 420+ (nightly)
          Platform: Macintosh
        OS/Version: Mac OS X 10.5
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: WebKit API
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: jim.correia at pobox.com


If you attempt to archive the main frame of a page like the attached one with
an empty iframe, during the archiving process an exception will be raised:

     *** -[NSCFArray addObject:]: attempt to insert nil

WebResource's designated initializer returns nil if there is no mainResource,
but the calling code doesn't handle this. Patch attached.

To reproduce archive the main frame of any product page loaded from amazon.com:

Reduced test case attached.
