           Summary: [Qt] Plugin asking for NPNVnetscapeWindow can crash
                    webkit
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: All
        OS/Version: All
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: New Bugs
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: christophe.oosterlynck at dzine.be


When using a QGraphicsWebview in a scene that is not viewed by any graphicsview, webkit will crash when the plugin asks for NPNVnetscapeWindow. If there is no graphicsview (client->ownerWidget() returns 0, see patch), asking for NPNVnetscapeWindow should return 0.
