PostGIS Geography data type not displaying in QGIS

I am trying to display data held in the PostGIS Geography type on a map in QGIS. Whatever I do I can't get it to work.

Here is the SQL that creates my data - a single point in London.

CREATE TABLE test_srid.world_points
(
  id serial NOT NULL,
  name character varying(150),
  geog_point geography(Point,4326),

  CONSTRAINT world_points_pkey PRIMARY KEY (id)
)
WITH (
  OIDS=FALSE
);
ALTER TABLE test_srid.world_points
  OWNER TO postgres;


CREATE INDEX idx_world_points_geog_point

  ON test_srid.world_points
  USING gist
  (geog_point);

INSERT INTO test_srid.world_points (name, geog_point) VALUES ('my_address', ST_GeogFromText('SRID=4326;POINT(0.1275 51.5072)') );

QGIS recognises this as a layer, but does not display any data:

I've spent a while looking through the documentation and can't find what I'm doing wrong. I'd be very grateful for any help. I have found this which seems to suggest that the geography type is supported.

Finally I've checked that the data in PostGIS is working correctly: I've created two points using code similar to the above, and run the following query:

SELECT ST_Distance(a.geog_point,b.geog_point)


from test_srid.world_points as a,
 test_srid.world_points as b

where a.id = 1 and b.id=2

The result came back as expected (I double checked against google maps).

Is there a setting I need to change to get this to work? I was initially working with QGIS Brighton, but upgraded to Wien to check it wasn't anything to do with my QGIS version.

Data in geometry datatypes displays with no issue.
