           Summary: [Qt] Crash closing QtTestBrowser after loading
                    www.orbitz.com
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
        OS/Version: Mac OS X 10.5
            Status: NEW
          Keywords: Qt
          Severity: Normal
          Priority: P2
         Component: Page Loading
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: yael.aharon at nokia.com


To reproduce the crash, open QtTestBrowser, load www.orbitz.com and close QtTestBrowser.
www.orbitz.com sends XMLHTTPRequest during the unload event and that is causing the crash.
