Loading this file and then saving it in the same name results in broken xlsx document
Created originally on Bitbucket by shadowobject
Executing this snippet of code
from openpyxl import load_workbook
wb = load_workbook('test.xlsx')
wb.save('test.xlsx')
results in a damaged xlsx document.
If you try to open it again with excel it reports a broken document and the contained chart is lost.
