Error at Access8Math initialization when running NVDA from source

[CyrilleB79]

Steps to reproduce

Just run NVDA from source with usual user config having Access8Math installed: runnvda.bat -c %appdata%\nvda

Actual behaviour

Error when the add-on is loaded upon NVDA start:

Expected behaviour

No error

I test Access8Math last commit is no error when running NVDA from source. Whether it is caused by other plugins, test to see the environment where only Access8Math addon is installed.

Thanks Woody for your answer. I have performed further tests and have reached the following conclusion. The error occurs when:

• NVDA is run from source
• Both the following add-ons are installed: Access8Math 3.3 and readFeeds 13.1.

Both add-on work well separately. Could you have a look at this conflict between these two add-ons?

Also cc @nvdaes, author of ReadFeeds add-on.
