I hope I have something more solid now.

1. I log into X (no xfconf daemon, settings daemon etc)
2. I open a term A and execute the following:

  strace -eopen xfconfd|&fgrep .xml

3. Next I open a new term B and execute the following:

  xfconf-query -c xsettings -p /Net/ThemeName

4. I see in term A the following files being read:

open("/home/mike/.config/xfce4/xfconf/xfce-perchannel-xml/xsettings.xml", O_RDONLY) = 6
open("/usr/local/etc/xdg/xfce4/xfconf/xfce-perchannel-xml/xsettings.xml", O_RDONLY) = 6

So, here it is doing something in the wrong order.

The xsettings.xml file in /usr/local has only the /Net/ThemeName and
IconThemeName.

Dropping that file "fixes" of course the problem.
