      Description

      Probably got the wrong component, but could not find any Cocoa component...

      When closing a QMessageBox that was shown after having dismissed an ApplictionModal dialog (see attached example from other bug), there is a crash in QCocoaEventDispatcherPrivate::cleanupModalSessions() . This might be due to the fact that the dialog is the only top-level window in the application and closing it triggers the application to tear down already.
