Column Security Queries generated by FORMS Performs bad on 11g(11.1.0.7)

Question

We are busy Upgrading our DB from 10g (10.2.0.4) to 11g (11.1.0.7).
We are currently using Oracle Application Server (10.1.2.0.2) with Form and Reports connecting to our 10.2.0.4 DB.
The Application Server is not being upgraded as there are compatable with 11g.
However when we point these 10g FORMS to the 11g DB we have huge performance issues on specific queries generated by FORMS if Block Propoerty "ENFORCE COLUMN SECURITY"=Y.
The query that 11g strugles with - for example is:
SELECT obj.object_type, obj.object_name, obj.owner
INTO :b0, :b1, :b2
FROM
(SELECT o.object_type, o.object_name, o.owner
FROM all_objects o,
all_synonyms s
WHERE s.synonym_name = :b1
AND s.owner = :b2
AND s.table_owner = o.owner
AND s.table_name = o.object_name
) obj
WHERE obj.object_type IN ('TABLE', 'VIEW', 'SYNONYM');
This query executes for almost 60 seconds - to check the Users Privs to access an Object.
Question:
HAS ANYONE ELSE EXPERIENCED THIS DURING thier 11G upgrade???
I would love to hear from other people with a similar technology if - hoe they have resolved these as it is NOT CODE THAT WE have CUSTOM written, IT IS ORACLE generated code that is performing so terrible on 11g*.
All feedback welcome.
PS: Our solution is to DISABLE Column Security on all our Forms as we control access via our own Security module.
