Procedure editing bug

Hello,

When I open procedure properties dialog and open "SQL" tab, it contains corrupted procedure definition, i.e.

Instead of

CREATE OR REPLACE FUNCTION "testProc"(IN "in_Param1" "varchar", IN "in_Param2" int4, OUT "out_Param1" int4, OUT "out_Param2" "varchar") AS
$BODY$
select 1, '2'::varchar
$BODY$
LANGUAGE 'sql' VOLATILE SECURITY DEFINER;

I get

CREATE OR REPLACE FUNCTION "testProc"(IN" in_Param1" "varchar", IN" in_Param2" int4, OUT" out_Param1" int4, OUT" out_Param2" "varchar") AS
$BODY$
select 1, '2'::varchar
$BODY$
LANGUAGE 'sql' VOLATILE SECURITY DEFINER;

I use pgAdmin 1.4.0 (Nov 5).

Best regards,
Alex Tyagloff
