qa: Intermittent AssertionError in `wallet_address_types.py` #19139

https://travis-ci.org/github/bitcoin/bitcoin/jobs/692067912#L5040

One more: https://travis-ci.org/github/bitcoin/bitcoin/jobs/721444891#L3297

Do we have any more recent failures? Both logs linked have expired. If this hasn't been seen recently then I think this can be closed.

It would be good to include an excerpt the next time this is seen

There is a failure in this test here: https://cirrus-ci.com/task/5241926094946304

But it isn't an AssertionError so it is likely a different issue.

EDIT: This isn't specific to wallet_address_types.py, just coincidence. Also seen here in p2p_dns_seeds.py: https://cirrus-ci.com/task/4818027771330560

Should probably make a new issue for this.

Maybe #23089 (review)

Is this still an issue with a recent version of Bitcoin Core? If yes, what are the steps to reproduce?
