Details:

This is a bug reported in Debian

      http://bugs.debian.org/610659

I reproduce the relevant part of the report here:

---------------------------------------------------------------

Drawing a line with 3D coordinates makes it impossible to draw more lines.
Following commands demonstrate this problem:

octave-3.2.4:1> line([0 10], [10 10])
octave-3.2.4:2> line([0 10], [10 10], [])
octave-3.2.4:3> line([0 10], [10 10], [0])
error: number of rows must match (1 != 2) near line 449, column 37
error: called from:
error:   /usr/share/octave/3.2.4/m/plot/__go_draw_axes__.m at line 449,
column 22
error:   /usr/share/octave/3.2.4/m/plot/__go_draw_figure__.m at line 92,
column 3
error:   /usr/share/octave/3.2.4/m/plot/gnuplot_drawnow.m at line 99, column
5
octave-3.2.4:4> line([0 10], [10 10], [])
error: number of rows must match (1 != 2) near line 449, column 37
error: called from:
error:   /usr/share/octave/3.2.4/m/plot/__go_draw_axes__.m at line 449,
column 22
error:   /usr/share/octave/3.2.4/m/plot/__go_draw_figure__.m at line 92,
column 3
error:   /usr/share/octave/3.2.4/m/plot/gnuplot_drawnow.m at line 99, column
5
octave-3.2.4:5> line([0 10], [10 10])
error: number of rows must match (1 != 2) near line 449, column 37
error: called from:
error:   /usr/share/octave/3.2.4/m/plot/__go_draw_axes__.m at line 449,
column 22
error:   /usr/share/octave/3.2.4/m/plot/__go_draw_figure__.m at line 92,
column 3
error:   /usr/share/octave/3.2.4/m/plot/gnuplot_drawnow.m at line 99, column
5

So first line([0 10], [10 10]) draws line correctly, but if I try to draw
that
line again after trying to draw an invalid 3D line, it's not possible any
more.
