Sensors Plugin Settings Keep Resetting

[David McKenney-Barschall]

The Sensors Plugin on my panel intermittently resets all settings, returning to just saying "sensors" or something and not displaying any temperatures.

It doesn't happen every time, but it happens fairly often. I suspect it may coincide with software updates, but I really don't know, because it seems to happen after a restart.

lsb_release -rd
Description: Ubuntu 18.04.4 LTS
Release: 18.04

apt-cache policy xfce4-sensors-plugin

What I did:
* Set my sensors plugin to display three temperatures without labels
* Use my computer, as usual, for a while, including restarts and updates and all sorts of stuff
* Start up my computer today

What I expected:
* Sensors applet to retain settings, like most reboots.

What I got:
* Sensors applet reset to settings different from those I had left it with.
