Details:

Here is how to reproduce the error:


graphics_toolkit('gnuplot');
demo trimesh


Instead of the expected figure window with a funny 3D plot, you'll get several
pages of error messages from gnuplot.

The trimesh demo works fine with fltk. But the gnuplot errors are still there
with the octave version 3.8.2-rc1.

I've observed this under Linux, but I assume it'll be the same for other
operating systems.
