Hardcoded in update-mime-database.c.

        env = getenv("XDG_DATA_DIRS");
        if (!env)
                env = "/usr/local/share/"PATH_SEPARATOR"/usr/share/";
        dirs = g_strsplit(env, PATH_SEPARATOR, 0);
        g_return_if_fail(dirs != NULL);
        for (n = 0; dirs[n]; n++)

I don't think that the values hardcoded in update-mime-database.d are
propagated to client applications.

That was what I was thinking too.  The question is which library that
is.  libxdg_basedir?  Sounds plausible, but evince doesn't use it.

Did you mean: xdb? ;-)
