Fresh install 14.04.2 on this machine, connect BT devices (headset, BT
mouse or mobile phone). They are all working normally. Installed package
plainbox-provider-certification-client 0.17 and plainbox-provider-
checkbox 0.21 and try to reproduce the issue. It is also can not
reproduce any more.

I guess it could fixed by update BISO && re-install 14.04.2.
