Title:
  Camera doesn't start on arm64 - crash in
  AalServicePlugin::devices(QByteArray const&)

Status in camera-app package in Ubuntu:
  New
Status in qtubuntu-camera package in Ubuntu:
  New

Bug description:
  Camera crashes on startup on arm64

  It's possible the reason is the lack of media-hub (bug #1618416), but
  camera should probably not die because of that.

  $ system-image-cli -i
  current build number: 23
  device name: frieza_arm64
  channel: ubuntu-touch/staging/ubuntu
  last update: 2016-08-30 09:13:12
  version version: 23
  version ubuntu: 20160830
  version device: 20160824.0
  version custom: 20160830

  Steps:
  * flash the above channel (remember --device frieza_arm64)
  * launch camera
