Fixed on the stable branch in this changeset (http://hg.savannah.gnu.org/hgweb/octave/rev/248d05c413dc).  The reporter can wait for the expected stable 3.4.3 release in the next month or build from source to see the fix.

line() now actually validates its inputs to prevent putting the graphics toolkit into an unrecoverable state.

I am not able at present to work on this bug, so I'm de-assigning it from myself. It doesn't happen with the fltk backend, if that's any help. However, with the fltk backend, this code does not produce a 3d line, nor does it produce any error at all.

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.
