@diddledani The error does have an impact on the Firefox snap running under KDE, which I can only presume does some poor parsing of xdg-settings output (including stderr?) when determining if it is itself the default browser.
BTW, the patch in https://gitlab.freedesktop.org/xdg/xdg-utils/-/merge_requests/52 is wrong (see my comment at https://gitlab.freedesktop.org/xdg/xdg-utils/-/merge_requests/52#note_1488548), use the attached patch instead.
With this, the Firefox snap recognizes itself as the default browser for me.
