           Summary: Startup crash on Qt platform
           Product: WebKit
           Version: 420+ (nightly)
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: Platform
        AssignedTo: webkit-unassigned at opendarwin.org
        ReportedBy: zack at kde.org


When calling FrameQtClient::openUrl for the first time, the owned frames
doesn't have a document set on it at all. In turn ResourceLoader depends on the
DocumentLoader in order to work and Qt's ResourceLoaderManager depends on it
being present in order to set Frame (in order to call checkLoaded). openUrl
used to let through creation of ResourceLoader with no parent document which
causes crashes due to above described dependencies. The patch explictly creates
an empty document if one isn't already present.
