I see boot there correct obexd initialization and that's all. I don't know if you even have paired the computer with N900. Let's try to remove pairing from computer and also from N900 (Settings -> Bluetooth -> Device(s)). For sure you can also: 1) kill obexd 2) stop bluetoothd 3) remove content of /var/lib/bluetooth 4) enable bluetooth debug (in /etc/event.d/bluetoothd change "exec /usr/sbin/bluetoothd -n" to "exec /usr/sbin/bluetoothd -n -d" 5) shutdown the phone 6) start the phone 7) pair phone with the computer 8) try the file transfer
