Here is what I am running...

coverage run --source=gfsad setup.py test
coverage html 

Those two work just fine and results are as expected. But when I run:

coverage xml

I get the following:

@JustinWP Can you provide me a reproducible test case? Even if it's a repo with your project, or a zip file with your code in it? I've never seen that error before, and I don't understand what the XML report would be doing that the HTML report would not.

Just cloned it and tried on a fresh install of ubuntu with same result.

Thanks, I can reproduce the issue with this repo. It's because of gfsad/utils/countries.py, which is an unusual file :)

I am still seeing this error even in your 4.0a5 branch (which is the version that has the fix based on the commit above). Any thoughts as to why this would be?

[nedbat]

4.0a5 was released on 16 Feb, the day before this fix.

BTW: countries.py has changed, but this is the version that caused the crash: https://github.com/justinwp/croplands/blob/83874e8efd532d2efe324231ec8875377cd9759a/gfsad/utils/countries.py
