Description
I have an application that has a welcome page written in QML with a QQuickWidget; when the user presses a button I'd like to switch to the main application view (like QtCreator does).
I have a QMainWindow with a stack widget in which I put a QQuickWidget and my application widget.
I trigger the switch between QQuickWidget and MyWidget from QML code. When I close the application I have a segfault deep inside Qt.
In the attached example I made a minimal application that replicates the problem. I've seen that:
- calling hide() on QQuickWidget from within QML code leads to a crash;
- calling hide() on QQuickWidget from C++ code doesn't crash;
Here is a sample stacktrace:
