xls-dump.py on an "empty" XLSX file crashes #4
Description
I created a new empty spreadsheet in Excel Version 1902 (Build 11328.20158 Click-to-Run), and saved it. If I run xls-dump.py on that, it fails:
$ ~/src/mso-dumper/xls-dump.py --dump-mode=canonical-xml --utf-8 --catch ~/Work/empty.xlsx
Traceback (most recent call last):
