I just tested 2.81-5359b7a03307 (2019-07-30) and the bug is reproducible too.

I'm not very familiar with Python's release cycle but it seems fixes were merged in the 3.7 branch in July 2018 and November 2018, so I assume the bug might be fixed with 3.7.2 and later.

Blender 2.80 seems to ship with 3.7.0, is there a specific reason to stay on that earlier release?

Worst case, since Blender ships its own Python build, it would be possible to backport the patches -- or work it around on the Blender side with some try/except statements. It's a bit sad to hit a bug when you want to report a bug :)

I found that it fails the first time you click the link, but seems to work on subsequent calls. (It's also not only related to Help > Report a Bug but any link meant to open in the browser). I'll send a patch that retries once on error.

We upgraded to Python 3.7.4, this should be fixed now.
