           Summary: [Qt][WK2] WebKitTestRunner is dead
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebKit2
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: kbalazs at webkit.org


Poor WTR is always crashing on termination. This is a regression since r71409.
The killer is me. In r71409 I haved connected the QSharedMemory object's deleteLater
slot to QCoreApplication::aboutToQuit to force deletion when the SharedMemory is
leaking on termination. The unsafeness of this approach is appearing when the SharedMemory's
dtor is called after aboutToQuit had been emitted. In that case we are trying to delete an
already deleted object and ending up in a crash. This is the situation in WTR when the UI process
is terminating. (Ok, it is not really a UI process).
