powerline-shell.py breaks with ValueError

[Datamance]

Here's what I see on my stacktrace:

Traceback (most recent call last):
  File "/Users/ricorodriguez/powerline-shell.py", line 692, in <module>
    add_fossil_segment(powerline)
  File "/Users/ricorodriguez/powerline-shell.py", line 685, in add_fossil_segment
    _add_fossil_segment(powerline)

  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/pickle.py", line 966, in load_string
    raise ValueError, "insecure string pickle"
ValueError: insecure string pickle

Also notice that when the bash script gets run, my prompt gets deleted entirely. Pretty sure that's because the script isn't running but the documentation could be clearer as to what I should expect (also in what order to do things)

I am having this same issue. Only on Mac.

I believe this is a duplicate of this. #236
It's caused by a bug in python. https://bugs.python.org/issue26083
You can download the latest verison of python 2.7.12 here https://www.python.org/ftp/python/2.7.12/python-2.7.12-macosx10.6.pkg
