Logging in as a normal user (non admin) generates errors in the Home Assistant logs

(Running v0.96.3)

These errors have been appearing in the logs for a while, but I’ve only just confirmed when the occur.

For each login as a normal (i.e. non-admin) user, the following error is recorded in the logs:

Error handling message: Unauthorized
Traceback (most recent call last):
  File "/srv/homeassistant/lib/python3.6/site-packages/homeassistant/components/websocket_api/connection.py", line 84, in async_handle
    handler(self.hass, self, schema(msg))
  File "/srv/homeassistant/lib/python3.6/site-packages/homeassistant/components/websocket_api/commands.py", line 52, in handle_subscribe_events
    raise Unauthorized
homeassistant.exceptions.Unauthorized: Unauthorized

These errors do not occur when logging in using my admin account.

Is this currently expected behaviour, or should I be looking to file an issue against the authentication / user component?
