I have attached a comment to this ghostscript bug report: https://forum.manjaro.org/t/ghostscript-problem-april-2019/81385/21.

Afaiu, that is a bogus warning when ghostscript uses fontconfig to enumerate the installed fonts.
I don't understand ghostscript or fontconfig good enough to know what has to be done to avoid or suppress this warning.

This warning message occurs under some conditions when plotting. The problem started in 5.2.0 but did not occur in 4.4.1.

This code exhibits the problem:

figure(1, 'visible', 'off')
fprintf('Plot a graph using %s\n', graphics_toolkit )
set(0, 'defaulttextfontsize', 25)
xrange = 1:10;
plot(xrange, [ssd; mean(ssd)*ones(1,10)], 'Linewidth',2);
legend('Actual','Average over touch')
axis([0, xrange(end)+2, min(ssd)-5, 5+max(10,max(ssd))])
xlabel('Row number', myfont{:})
ylabel('Milliseconds', myfont{:})
title('Standard Deviation (Touch only)', myfont{:})
grid ('on')
print (1, [graphics_toolkit, '1.png'], mywidegraphs{:})
fprintf('Graph plotted\n')
