I tried to duplicate your problem and couldn't:

z=# create user cib_admin;
CREATE USER
z=# create group cib_all user cib_admin;
CREATE GROUP
z=# create group cib_trusted user cib_admin;
CREATE GROUP
z=# create table sometable(f1 int);
CREATE TABLE
z=# REVOKE ALL ON sometable FROM PUBLIC;
REVOKE
z=# GRANT SELECT ON sometable TO GROUP cib_all;
GRANT
z=# GRANT INSERT ON sometable TO GROUP cib_trusted;
GRANT
z=# GRANT UPDATE,DELETE on sometable TO cib_admin;
GRANT
z=# \c - cib_admin
You are now connected as new user cib_admin.
z=> select * from sometable;
f1
----
(0 rows)

z=> insert into sometable values(1);
INSERT 281986 1
z=> update sometable set f1=0;
UPDATE 1
z=> delete from sometable;
DELETE 1

Could you provide an exact test case? Also, which PG version are you
running? (I'm testing CVS tip = 7.3beta1+)
