I logged in as user1 (which has sudo privilege) at a console, and ran
sudo adduser user2 sudo
then rebooted and logged in to the GUI as user2 .

I then  (as user2) opened a GUI terminal and ran
sudo -Hu user1 dbus-launch gsettings list-schemas | grep org.mate |
xargs -n 1 gsettings reset-recursively
as advised.

It returned "No protocol" then reset the panel settings for user2.

So, the panels are still broken for user1, and, now, the panels
settings for user2 are returned to the default settings.
