Qt/QML application crashes at start-up in Debug Mode

I'm using Qt 5.3 mingw on windows and writing application with Qt/QML (the application is a combination of qt and qml, and the qml
is embedded in QMainWindow).

sometimes, a crash happens at start-up when I run the project in Debug mode and trying to debug the code.

Code:

---

the inferior stopped because it received a signal from operating system

---

Is there any problem with QML or something else? the stack is like this when error happens.

Code:
