I've got a ZelHer P20 headset and a W520 Lenovo laptop, the same problem occurs.
What I observed is that during the first 60 seconds of activating the P20 headset, running bt-adapter -d will display the Name: (null) and in the bluetooth-wizard, it only shows the bt address (mac-like format).
After about 60 seconds of the headset in pairing mode, re-running bt-adapter-d, the name field is now populated. After the name field is present, pairing can be complete.
So, while clearly gnome-bluetooth should handle the case where name is null, there may be a workaround if you can keep your device in pairing mode long enough so that the name of the adapter appears.
