Unless Martin will be able to resolve the issue "properly", I guess
the only way of shutting up the warning is to use
g_log_set_writer_func to temporarily set the glib log writer function
to a dummy one that does nothing, then restore the original writer
function.  That's gross, but what else can be done when you deal with
libraries which think they are smarter than you are?..

Thanks.
