        * gtype.c (check_add_interface_L): applied patch from Matthias Clasen
        <maclas@gmx.de> to check for prerequisite of interfaces, fixes #74427.
        fixed mutex recursion in his patch (we can't call g_type_is_a() while
        holding a read lock).

        * gparam.c (canonalize_key): cleanup.
