Comment 60 for bug 1509139

I am not sure if this should go here as well (please tell me whether I should open another bug for that).

I am running KDE5 on Arch Linux and cannot xdg-settings set default-web-browser either.

Running with XDG_UTILS_DEBUG_LEVEL=3 I obtained:

> $ xdg-settings set default-web-browser chromium-browser.desktop
> Running KDE trader query "text/html" mimetype and "Application" servicetype
> make_default_kde: No kde runtime detected
> make_default_generic chromium-browser.desktop text/html
> Updating /home/username/.local/share/applications/mimeapps.list
> Running KDE trader query "text/html" mimetype and "Application" servicetype
> make_default_kde: No kde runtime detected
> make_default_generic userapp-Firefox-65I9HY.desktop text/html
> Updating /home/username/.local/share/applications/mimeapps.list

I dug a bit deeper into this and noticed, that xdg-mime still has some parts which are not aware of KDE 5. I attached a patch which does some superficial fixes but it is not working although the output changed:
