[Gnuplot-info] Fontconfig warning

Using the current main branch I started getting a warning that I haven't 
seen before:

Fontconfig warning: using without calling FcInit()


In my scripts the line triggering this warning looks like this:

set title 'title' font "DejaVu-Sans-Bold,25"

font size specification is not a problem, just the call. The warning 
will not appear if the line is commented out.


Note that the same scripts start with lines of the type:

set terminal pngcairo enhanced size 1400,900 font "DejaVu-Sans,13"

where the font call is not triggering a warning.


What could be going on?
