qmlscene crashes on music-app exit

[Alan Pope 🍺🐧🐱 🦄]

Add the music app to the desktop from the daily ppa:-

https://launchpad.net/~ubuntu-touch-coreapps-drivers/+archive/daily

Install the music-app.

Run music-app by searching for "Music" from the dash.
Play some music, close the app with the close button in the qmlscene window.
This generates a crashdump for me.

https://errors.ubuntu.com/oops/4d725aae-ce65-11e3-8e02-fa163e373683 is an example of one.

Based on the stacktrace it'd look like Qt Grilo related, and maybe related to the recent addition of mediascanner depedency.
