This crash was retraced on mako from a .crash file received from Weather App logs: http://ci.ubuntu.com/smokeng/trusty/touch/mako/206:20140224:20140224/6796/ubuntu_weather_app/
Edit: the duplicate bug #1284998 has another retrace from image 207's calculator-app. These two apps seem to continue to produce this crash.

Marking the bug as Incomplete to indicate it's probably not reproducible anymore. Qt Declarative script engine was rewritten in the Qt 5.2.1 and it's likely the crashes that happened with Qt 5.0.2 do not happen or are different with the new Qt.
