Problem with printing plots

[Jordi Gutiérrez Hermoso]

I'm seeing the following problem when trying to build the docs:

    make[3]: Entering directory
`/home/jordi/coding/build-vcs/dbg-dev-octave/doc/interpreter'
    ../../run-octave -f -q -H -p
/home/jordi/coding/vcs/octave-devel/doc/interpreter --eval
"geometryimages ('voronoi', 'eps');"
    error: get: A(I): index out of bounds; value 3 out of bound 2
    error: called from:

    make[3]: *** [voronoi.eps] Error 1

Using hg bisect, I have tracked it down to this cset:

    changeset:   14413:4f160344236a

What's going on with this cset? It doesn't even have a commit message.
I think I missed this one.

TIA,
