I see... the problem is I don't know what application/x-extension-html is supposed to be used for, so I'm tempted to close this as wontfix. Berto

I'm not familiar with it, it looks like WebKit doesn't know about it either and treats it like binary data. Berto

Looks like it's sufficient to remove ~/.local/share/mime/application/x-extension-html.xml and then to regenerate database: update-mime-database ~/.local/share/mime More information is available in bug #722279, which is very similar to this one. In short, libwebkit2gtk doesn't like "application/x-extension-html" and decides to not render such documents.

I think ~/.local/share/mime/packages is the "source code", and everything else is generated from those. The only files I have in ~/.local/share/mime have come from either Wine associating various Windows-related formats with itself, or the GLib test suite using "application/x-extension-gio-tests" to make sure this is still something that is possible to do. I would guess that the most likely root cause would be some sort of misconfiguration for text/html or a related file type, which might make devhelp misinterpret HTML files as something that it doesn't know how to load? smcv

Created a new user and devhelp works. So, I'm not sure what is stopping it from working for my current user. Results are the same across Xorg/Wayland.

I don't know. I don't have Chrome installed, and I don't get that warning. I'm surprised devhelp gets EPERM reading files in /usr/share/doc that I would have expected to be world-readable. Are the permissions on any element of that that path more restrictive? Or is this maybe an AppArmor proplem?

This is working fine for me, with the same package versions and even the same locale that you report, so there must be more to it than that - perhaps some configuration or system difference that is making this work for me but not for you. Over in Ubuntu, Jeremy sees this problem but Sebastien Bacher does not, so again there's probably some system configuration difference that triggers this. If you run devhelp from a terminal (gnome-terminal or xterm or equivalent) and click on one of the manuals, what messages does it produce? Is anything logged in the systemd journal when this happens? smcv

Yes, I reported a similar issue on Ubuntu, but hadn't gotten around to testing on Debian yet. Ubuntu's webkit2gtk packaging has diverged a bit so I didn't know whether Debian was affected too. Let's reassign to webkit2gtk. https://launchpad.net/bugs/1942951 Thanks, Jeremy Bicha
