The app in question is Evolution 3.22.6. My distro is Fedora 25,
updated from the stable repos this morning, and running with the latest
stable KDE/Plasma desktop:

$ xdg-settings get default-web-browser
opera.desktop
$ xdg-settings get default-url-scheme-handler
$

So no URL handler and the browser is Opera. Opening the KDE Settings
panel shows the same thing. However if I use gnome-control-center to
check the defaults, the browser is Firefox, not Opera, and indeed
Firefox is what opens when I click on a link in Evolution. In fact
Opera is not even offered as an option.

So something is inconsistent. Since the underlying XDG tool is
supposedly what offers compatibility, I assume it must be Gnome.
