octave-2.9.10 stem cmd

[A. Scottedward Hodel]

Under Mac OS 10.4.9, Intel-Mac (Macbook pro) octave -2.9.10, I am encountering an error when using the stem command.

The first example in the stem help file shows the problem.

octave:6>           x = 1:10;

octave:7>           stem (x);

error: invalid conversion from string to real matrix

error: invalid RGB color specification

error: set: expecting argument 2 to be a property name

error: evaluating if command near line 61, column 3

error: called from `__line__' in file `/usr/local//share/octave/2.9.10/m/plot/__line__.m'

error: evaluating assignment _expression_ near line 35, column 7

error: evaluating for command near line 111, column 3

error: called from `stem' in file `/usr/local//share/octave/2.9.10/m/plot/stem.m'

The details of the underlying code are beyond a quick fix on my part.  Can anyone duplicate this error?
