Legend colors

I seem to experiencing a bug when doing bar charts and display a legend.
I'm calling the figlegend properly I think with a reference to the objects
returned from the bar() calls. The problem is both color patches in the
legend appear orange. Any ideas?
I'm using matplotlib0.87.7, Python2.5, and Numpy 1.0.

for i in range(len(cpu)):
    t.append(i + 0.25)
plot9(nodes, t, cpu, wait)
