octave w/ gnuplot backend produces bad pdf

[Dmitri A. Sergatskov]

The following octave scrip produces a bad pdf

(similar to one in  https://bugzilla.redhat.com/show_bug.cgi?id=1340660 )

graphics_toolkit ("gnuplot")
x=linspace(-1,1,11);

y=0;

z=x;

mesh(x,y,z);

colormap([0,0,0]);

print("bad_pdf.pdf", "-dpdfcairo")

====

A gnuplot script tat demonstrates the problem is attached (it contains binary data).

Both firefox and chrome would render pdf anyway, but evince/xpdf/okular would not.

I suspect the problem with octave's

colormap([0,0,0])
command here.

But I also think that gnuplot should not produce bad pdf.

Dmitri.
