[Webkit-unassigned] [Bug 17948] New: Exception in -[WebDataSource webArchive]

           Summary: Exception in -[WebDataSource webArchive]
           Product: WebKit
           Version: 523.x (Safari 3)
          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: mjt at c-command.com


I've seen several cases where WebKit raises an exception:

-[NSCFArray insertObject:atIndex:]: attempt to insert nil

when my code calls [[[webView mainFrame] dataSource] webArchive]. I've been
able to reproduce this only rarely on my Mac, but I have a customer for whom it
happens 100% of the time, no matter the page.

As far as I can tell, the exception is being raised in -[WebDataSource
subresources]. It looks like the WebResource that's being created in the loop
is returning nil from its -init method. While there may be an interesting and
significant reason for that, I suggest that -subresources refrain from adding
nil objects to the array so that at least a partial Web archive can be
returned.
