I'm okay with doing that for this particular warning, and the
appropriate option already exists (the G_DEBUG environment variable can
be set to `fatal-warnings', which will cause GLib to abort upon
encoutering such a warning, even if we filter it out.)

But I don't know whether or not it's okay to treat all warnings that
way.  For example, bug#53900 is a serious bug that got caught by someone
noticing a warning emitted by GTK, and presumably wouldn't have been
reported if the warning had been filtered out.

Thanks.
