Details:

When the result of a logical expression is passed to stem as the y argument
this error occurs:

n = -10:10;
x = n >= 2;
stem(n, x);
error: invalid value for array property "ydata"
error: called from:
error:  
/usr/local/octave/3.8.0/share/octave/3.8.0/m/plot/draw/private/__stem__.m at
line 135, column 7
error:   /usr/local/octave/3.8.0/share/octave/3.8.0/m/plot/draw/stem.m at line
127, column 8

The strange thing is that the graph gets plotted correctly, but the execution
of the program stops.
If you do this:

stem(n, 1*x)

no error occurs.
