The NetworkManager - as it is for now (14/03/10) - doesn't handle the bnep0 interface. The interface is created by bluez-4.61 daemon. It emulates the ethernet connection between my desktop PC (linux) and my notebook (winxp).

The following message can be found in the logs after a bluetooth connection:

>>>>>>>>>>>>

                - Last output repeated twice -

<<<<<<<<<<<<

Steps to reproduce:
1) Linux: start bluetoothd daemon.
2) WinXP: connect to my desktop PC via PAN service.

Actual results:
NetworkManager-applet shows nothing about the new interface.

Expected results:
NetworkManager-applet shows the new interface and allows to create manual or automatic connections via it.
