Comment 2 for bug 1288885

I notice that weather has a export QT_SELECT=qt5 prior to calling qmlscene, whereas music-app does not.
#!/bin/bash
export QT_SELECT=qt5
qmlscene /usr/share/ubuntu-weather-app/ubuntu-weather-app.qml
pat@pat-samsung:~$ more /usr/bin/music-app
#!/bin/bash
qmlscene /usr/share/music-app/music-app.qml
They both work properly on my system, but mine is not quite a clean install, and perhaps installing the SDK effects this.
Other compiled apps like reminders not invoked with qmlscene will work as well
