I keep on receiving bug reports about Machines vs. Machines being crashy

- sound effects enabled, the game seems very stable.
+ 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 be give the system a hard time and reveal most of the crashes
eventually.
