BUG: pgAdmin III View table with empty strings

Version: 0.8.0 (Jul 14 2003), Win32 version

Steps:
1) create table with one varchar column
CREATE TABLE public.test
( a varchar(50) NOT NULL
) WITHOUT OIDS;

2) fill it with some empty strings
INSERT INTO test(a) VALUES('')

3) run pgAdmin III, select table and choose view data from popup menu

4) pgAdmin III shows two apostrophes ('') instead of empty strings.
