[Po-Hsu Lin]

Steps:
1. Download 16.04.2 dailylive (Feb.9) image and boot to live desktop
2. Run mythbuntu-control-centre from a terminal

Results:
* I can open mythbuntu-control-centre and it looks ok, but I can see these errors from the terminal.

(This issue can be found in 16.04.1 Mythbuntu image as well)
