There used to be 2 problems. One is the one described in the thread
referenced above. The other was fixed recently and was due to the
text/binary pipe mode for the communication between octave and
gnuplot: octave used binary mode, while gnuplot used text mode.
This was a problem when sending binary data: this is the case when
octave sends the colormap to gnuplot.
All problems should be fixed now.

If you want, I can send you a patched gnuplot executable in private.
