Allowing comment for empty cell (Attribute NoneType)
*Created originally on Bitbucket by [megavolts](https://bitbucket.org/%7Bb8759c7a-b72f-482f-8f7d-4ff9c2150a84%7D/)* Today, I got the following error "AttributeError: 'NoneType' object has no attribute 'read'" when saving a file I opened with keep_vba=False. The error comes from empty cells that have a comment, e.g. Sheet S_ice, Cell J6, K6, L6. Adding text/number within the cell fixed the problem. I propose to allow comment for empty cells. *Attachments:* [BRW_CS-19990312.xlsx](/uploads/6f177ef12b89860d29dc3db6ccad26d6/BRW_CS-19990312.xlsx)
