Unable to process tutorial file

Created by: smach

After downloading the tutorial data file, when I try running

in2csv ne_1033_data.xlsx > data.csv

I get the error message

'NoneType' object is not iterable

This seems to be an issue with this specific tutorial file, because I was able to import my own small test spreadsheet OK. Someone may want to take a look at that tutorial test-data spreadsheet. FYI I tried importing it into R a couple of different ways, one way worked fine but another way choked saying 'invalid sheet xml'.

I'm running csvkit on OS X Yosemite with the standard Python installed by default (2.7.6).
