openpyxl: remove_sheet causes IndexError: list index out of range error on saving sheet

Created originally on Bitbucket by Jim98 (Jim Pisano)

Python 3.4.4 / Excel 2016 / openpyxl 2.4.1

I am trying to use openpyxl to:

1. Open an Excel (2016) workbook which contains 3 worksheets (Sheet1,Sheet2,Sheet3)

2. Remove a worksheet (Sheet2)

3. Save the workbook to a different workbook minus Sheet2

#!python

from openpyxl import load_workbook
wb = load_workbook("c:/Users/me/book1.xlsx")
ws = wb.get_sheet_by_name('Sheet2')
wb.remove_sheet(ws)
wb.save("c:/Users/me/book2.xlsx")

The wb.save will generate an IndexError: list index out of range error and produce a corrupted book2.xlsx file which Excel cannot open.

The above code generates the following error

#!python
