Sure, the commands where it crashes and the output are:

print dates
pyplot.axis([0, len(prices.label[0]), -1.5, 1.5])



OK, here is where the problem is.  In the plt.axis call you are setting the x-axis min to 0 which is not a legal date value.  I suggest letting the x-axis take care of itself, and set the y-axis limits with 

plt.ylim(-1.5, 1.5)
