ORA-08103: object no longer exists

Hi, sorry in advance for my bad engliI have a strange problem.

If I try to make this sample statement:
select count(*) from visite where data = '10-jun-96' and id_utente =
'000255';

 i take always the error in subject.
But if the statement is only select count(*) from visite where data =
'10-jun-96' or

select count(*) from visite where id_utente = '000255' all was ok.

I don't know why.

Thanks in advance.
