Ben, I tried restarting thermald (1.7.0-5) at least 10 times, and the system always see the same broken sensor, the same as in 1.7.0-4 and the same as in 1.7.0-6.
Perhaps by luck (or perhaps because some library or compiler version difference) thermald 1.7.0-5 worked fine on my ubuntu 18.04 setup. Thank you Ben and Colin Best regards Marc
