bug: repeated messages in pgadmin (1.18.0 Alpha 1) query tool messages pane

Hello,
I'm using pgadmin 1.18.0 Alpha 1 (compiled from
http://ftp.postgresql.org/pub/pgadmin3/release/v1.18.0-alpha1/src/pgadmin3-1.18.0-alpha1.tar.gz).

Messages are repeated multiple times in messages pane. Version 1.16.1
does not expose this behavior.

Example SQL:

DROP FUNCTION IF EXISTS raise_something () CASCADE;
CREATE OR REPLACE FUNCTION raise_something ()
RETURNS VOID AS
$BODY$
BEGIN    RAISE WARNING 'Something';    RAISE NOTICE 'Something else';
END
$BODY$
LANGUAGE plpgsql;

select * from raise_something();
