Defensive change to avoid crashing on weird large Excel files
Created originally on Bitbucket by aigarius (Aigars Mahinovs)
In file openpyxl / workbook / names / named_range.py line 127:
- node_text = name_node.text
- node_text = name_node.text or ''
This change avoided a crash and the data loaded from the files without further problems. Can not reproduce with other files and the ones that produce the bug are confidential :)
