Leap 15 - exo-preferred-applications:

If one wants to change the default Web browser to e.g. Chromium, using the
bundled "Preferred Application" App (exo-preferred-applications), it doesn't
update `x-scheme-handler/http` and `x-scheme-handler/https`, which leads into
odd behavior like xfce4-terminal opening links in the wrong browser via
Ctrl-LeftClick.

This can be fixed with:
$ xdg-mime default chromium-browser.desktop x-scheme-handler/https
$ xdg-mime default chromium-browser.desktop x-scheme-handler/http
