Plotting KeplerLightCurveFile makes my ipython session unresponsive

Problem description

After I successfully plot a KeplerLightCurveFile (from_archive), my entire ipython session becomes unresponsive. I am forced to close the terminal that the ipython session is contained within

Example

import lightkurve as lk
import numpy as np
import pandas as pd

from pylab import *;ion()

k201485699 = lk.KeplerLightCurveFile.from_archive('201485699')
k201485699.PDCSAP_FLUX.plot()

Then my ipython session crashes (stops responding) with no warnings or errors

Expected behavior

I would have expected the matplotlib window to open, and then I would be able to use my ipython session to continue to plot and/or make other code.

Environment:

• platform: OSX 10.13.6
• lightkurve version: 1.0b16
• installation method: pip install lightkurve

We release a new version every few days now!

@exowanderer I notice that you are turning interactive mode on using ion(). What happens if you remove that statement, or if you call ioff() and call show() manually after issuing the plot command?
