This always happens during the second device discovery run in
the current process. The first discovery doesn't have this issue.
As to why the discovery session remains active despite the previous one
being terminated is not known. This may be a bug in Bluez4.
To workaround this issue we have to wait for two discovery
sessions cycles.
