Code review comment for lp:~aacid/unity8/decodeAudioURIs

I'm going to declare this blocked until https://bugs.launchpad.net/canonical-devices-system-image/+bug/1449790 gets fixed because i need the media-hub to get fixed so that the layer on top of it can get fixed otherwise i'm not sure if i'm doing it right, wrong or workarounding media-hub bugs themselves.
