           Summary: [Qt] Crash when showing Flash content on
                    staples.com...
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: WebKit Qt
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: adawit at kde.org


If you visit staples.com and find the link that says "Weekly Ads" and click on it sends you to a page that is mostly flash content. If this does not already crash your QtWebKit based browser, simply reloading the page should.

Below is the back trace from QtTestBrowser (QtWebkit 2.1, webkit 533.3):
