if a magnitude is less than the minimum magnitude the plot crashes with a cryptic error

import vcs
import vcsaddons
import numpy

p = vcsaddons.createpolar()

p.list()

mag = [1,2,3,4,5]
angle = numpy.arange(5)/180.*numpy.pi

import vcs
x=vcs.init(bg=True)
p.x=x
p.magnitude_ticks = [7.,15.,25]
p.plot(mag,angle)

dies with:

Traceback (most recent call last):
