    Description

      If a QML StateMachine SignalTransition is connected to a signal from a QObject, and that object emits that signal from a QtConcurrent::run thread while in the object's destructor, then there is a crash in QSignalEventEmitter.

      I've attached a small example demonstrating the problem (it's a little more clear from the code)
