When I run gnuplot from the command line, I can run:

gnuplot
plot sin(x)/x


and get the expected output with a terminal time of qt.

It looks like there may be some missing parts in this recipe for
reproducing the bug?  Or did you mean "gp" instead of "gf" there at the
end?

In which case I get no errors, but just an empty gnuplot chart.

Oh, perhaps gf and then gp?  That gives me an error, but not the same
one you're seeing.

To reproduce, from emacs -Q:

M-x calc
vx 10 RET
RET
gf
gp

Thanks -- I can confirm that this fixed the bug here, too.
Applied to Emacs 28.
