Do you have CSSU installed ? It is (unfortunately ?) a prerequisite for running the QML GUI as Qt Components & PySide are badly broken on vanilla PR 1.3 Fremantle.
This looks like running under QML 1.0, which doesn't have PinchArea and some other types/properties. Still, it should have crashed sooner on import QtQuick 1.1, which should not be available without CSSU.
