Surprised this wasn't picked up by a unit test prior to landing in master...

Thanks for filing the issue, currently dev and master channels are reproducing this issue.
Although I see different logs. there have been no updates to the dev channel recently but I do have a multi-channel setup on the same machine, it is possible master channel introduced similar to the dev channel on my local setup, I don't see such an error on beta channel on the same system
Channel dev, 2.3.0-16.0.pre
