Title:
  gsd-rfkill-manager fails to receive rfkill event

Status in gnome-settings-daemon package in Ubuntu:
  Fix Released

Bug description:
  The default encoding for GIOChannel is UTF-8, but rfkill event is
  binary data. If the value is invalid UTF-8, gsd-rfkill-manager will
  fail to receive rfkill event.

  Steps: Run suspend/resume Test (> 127 times)
  Failure Rate: 100%

  In some platforms, bt will be re-probed after s3. If bt is re-probed,
  rfkill-idx will increase. And, 128 is the first invalid UTF-8

  $ rfkill list
  ID TYPE DEVICE SOFT HARD
  1 wlan phy0 unblocked unblocked
  128 bluetooth hci0 unblocked unblocked
