expected type error since 2.5.0

Created originally on Bitbucket by jdbothma (JD Bothma)

The attached spreadsheet opened fine in 2.4.9, 2.4.10 and 2.4.11 but I get the following error in 2.5.0 if I open it writable:

TypeError: expected <class 'openpyxl.descriptors.base.Integer'>

It works fine when I open it readonly but I haven't figured out how to check if a row is hidden when readonly.

This is how I open it: https://github.com/OpenUpSA/treasury-data-package-pipeline/blob/01cdffdc0dd3eb75938d506d87029211c42c5995/bin/epre.py
