           Summary: setPluginUnavailabilityReason can destroy renderObject
                    before obscurity check
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Macintosh Intel
        OS/Version: Mac OS X 10.8
            Status: UNCONFIRMED
          Severity: Major
          Priority: P2
         Component: Plug-ins
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: gordon_sheridan at apple.com


When creating a replacement object for blocked plugins, setPluginUnavailabilityReason can destroy the renderObject, so we need to call renderObject->isReplacementObscured() beforehand.
