Bug description:
  SRU JUSTIFICATION:
  An easy to reproduce crasher when changing settings for bluetooth headsets. It seems to be affecting a lot of people and the patches are not very intrusive.

  TEST CASE:
  1) Connect a bluetooth headset.
  2) Open bluetooth properties, select the added device.
  3) Click the Sound Settings button
  4) Move to the Hardware tab in the Sound Settings panel; then select the bluetooth headset device.
  5) Click Speaker Test; then click the Test button to start a sound test.

  * Without the patch and immediately after adding a new bluetooth headset device; you would see a crash of gnome-control-center: the control center application will disappear.
  * With the patch, the sound test completes and other sound settings are available.
