Device tracker error in 0.67.0b0

[point-4ward]

Home Assistant release with the issue:
0.67.0b0

Last working Home Assistant release (if known):
0.66.1b-something (I've missed at least one, been too busy this week!!)

Operating environment (Hass.io/Docker/Windows/etc.):
Debian / Venv

Component/platform:
Device tracker

Description of problem:
Since upgrade I get this error on every restart (see trace)

PLEASE NOTE - it's 11pm here so I can't say whether this is actually affecting presence detection, but the device tracker.see service is present in the services tab.

Problem-relevant configuration.yaml entries and (fill out even if it seems unimportant):

device_tracker:
  - platform: bluetooth_tracker
    new_device_defaults:
      track_new_devices: false

  - platform: gpslogger

ios:

Traceback (if applicable):

Additional information:

None yet, but will try an add to this when I can do some tests in daylight hours.

Just to confirm that presence detection appears to be working fine on the ios devices, in spite of the error.

Bluetooth isn't working.

Will have to wait to see about gpslogger, but I would guess that isn't either as the error message is talking about mac addresses, where the ios devices don't use that.

I can confirm same behaviour. Deleted known_devices.yaml, restarted HA and when BT-device is found, it generates this error without adding the device to known_devices.yaml:

I am running 0.67b0 through hassio beta channel.

[point-4ward]

Yeah, only Bluetooth is affected, gpslogger is working fine.

Can also confirm bluetooth tracker error in 0.67. Using latest hassio. Status on devices never updates.

Looks like it has to do with the MAC address that is being passed in, it chokes in our mac resolver. I am going to remove the mac resolver as we're leaking info on device vendors.

[jimbob1001]

Possibly unrelated but since updating to 0.67.0b1 bluetooth device mac addresses in known_devices.yaml are being prefixed with a double underscore, which then throws an error as it thinks the second underscore is part of the mac address...
