Creating and destroying SoundEffects causes crashes

Bug description:
I keep on receiving bug reports about Machines vs. Machines being
crashy on Ubuntu Phones and I tracked it down to the SoundEffect item.
When playing without sound effects enabled, the game seems very
stable.
To get to the bottom of this I created an app that simulates a bit how
a game works with sound effects. It's a bit more aggressive than
Machines-vs-Machines (still not really far fetched from a real game
scenario) and reliably triggers some crashers in less than a minute
here.
So far I've seen crashes in creating SoundEffects items as well as
removing them from the scene.
Please find the example here: lp:~mzanetti/+junk/soundcrasher
You should be able to run it on any vivid powered device by just
opening the .pro file in QtCreator and hit the play button. The logs
vary a lot between crashes. Sometimes I get some PulseAudio messages,
sometimes it just crashes without any. Probably some raciness. Anyhow,
this example app should give the system a hard time and reveal most of
the crashes eventually.
