sqlite3 via pdo for php5 on CI 1.6.1?

It seems that sqlite3 is not important enough

I'm using sqlite3 on my debian system with PHP 5.2.0 and CI 1.6.1.
In this post I explain (a bit) what I've done to get sqlite3 working:

It works for me while doing selects, doing an insert seems to give the following error:
SQL logic error or missing database


When I do $this->db->query('SELECT * FROM kado') it works good.
When I do $this->db->query("INSERT INTO kado (naam, omschrijving , jarige) VALUES ('22', '3', 1)") it gives the above error.
Running the query directly on the database from the commandline works good.
