Bluetooth daemon default configuration is wrong

I was trying to connect my Android device to python script via bluetooth connection. The connection raised fine but it was not able to make the connection. I am using [1] as server.

When looking at syslog i noticed:
> bluetoothd[707]: Unable to spawn pnatd: Failed to execute child process "/usr/bin/phonet-at" (No such file or directory)

Googling that gives [2]. And comment from 'Selmi' follows up to discussion on linux-bluetooth [3].

They say:
>There should be absolutely no reason for Ubuntu have this plugin enabled
or even compiled. You might wanna file a bug to them to disable it. The
only place where it makes sense to be compiled is in Nokia's Maemo
Harmattan platform. For everything else it should be disabled (as it is
by default).

And indeed, adding line
'DisablePlugins = pnat' to '/etc/bluetooth/main.conf' makes the test work fine.
