Date Picker no longer works in applications converted from v 3 to v4

Question

We cloned our current server and upgraded it to v4.0.2 of APEX.
We now get this error on all the pages that have a date picker:
ORA-01460: unimplemented or unreasonable conversion requested ORA-02063: preceding line from PMO_PROD
Unable to fetch row
I have tried to delete the date picker and recreate it but I get the same error.
I also get this error when I try to apply a currency format to a Text item.
Anyone has the same problem??
Thanks

Have exactly same problem running APEX 4.0 against a db. 9.2.0.7 via dblink. APEX Repositori is on Oracle express 10.2.
Test table on remote db is
CREATE TABLE "VISKMIG"."MIG_TEST" (
"IDENTNR" NUMBER NOT NULL ENABLE,
"CODICE" VARCHAR2(8 CHAR) NOT NULL ENABLE,
"DESCRIZIONE" VARCHAR2(2000 CHAR),
"DESCRIZIONE1" VARCHAR2(2000 CHAR),
"DESCRIZIONE2" VARCHAR2(2000 CHAR),
"DESCRIZIONE3" VARCHAR2(2000 CHAR),
"DATAINI" DATE NOT NULL ENABLE,
"DATAFINE" DATE,
CONSTRAINT "MIG_TEST_PK" PRIMARY KEY ("IDENTNR")
APEX is defined over a view
create or replace vies MIG_TEST as
select * from MIG_TEST@APEX_VISKMIG_DEV9I
where APEX_VISKMIG_DEV9I is the local dblink.
Moving the table on the local apex db solve the problem.
Difference are:
- accessing the table over a dblink ;
- the remote db is version 9.2
