Octave version 3.2.4 is very, very old and no longer supported. Please update to a newer version and re-run your code. If there is still a problem then this bug can be re-opened.

Incidentally, when I run your code on the latest stable version (3.6.2) I get this:

So part of the problem is that d2(:,4) is a column vector and not a matrix. You might be able to run contour correctly on version 3.2.4 if the third argument to contour is a matrix.

contourf() failed with what I believe to be valid input. I noticed it failed in an if statement which only ran if the plot was filled, so I tried contour() and Octave aborted.

This is running on Ubuntu 12.04 inside VirtualBox with a Windows XP host.
