Android: qmlscene crashes when closing the initial QFileDialog and trying to set up the scene

To reproduce, just build qmlscene as an Android application, install it and run it. Because a qml file is not given on the command line, it will open a QFileDialog first to prompt for one. Select a qml file and hit OK; then it crashes like this:

I made the following changes to qmlscene:

In qmlscene.pro, comment out
#load(qt_tool)

and in main.cpp, it's convenient to have a default starting directory where you keep your qml files:

Also in main.cpp, you can work around this bug by hard-coding a path to a qml file, so the file dialog will not be shown:
