v 0.7.0: Accessing out of bounds

[tomas789]

I did just

import zipline

%%zipline --start 2013-1-1 --end 2014-1-1 --symbols AAPL -o perf_dma

def initialize(context):
    pass

def handle_data(context, data):
    pass

And I got this error

AAPL

This may be a dup of: https://github.com/quantopian/zipline/issues/447 but I could not duplicate I got: TypeError: run_pipeline() got multiple values for keyword argument 'print_algo'

with my latest version of Zipline (0.8.0rc1)

I am unable to reproduce this on master. I believe that this was fixed and that it was related to #447
