The same is happening to me with the latest release.
I have created a table: 
CREATE TABLE foo (bar VARCHAR(30));

And when I query it with:
SELECT bar FROM foo;

I get:

org.hibernate.MappingException: No Dialect mapping for JDBC type: 0

On modifying the SQLiteDialect class as shown below, I'm able to overcome the 
discussed problem.

public class SQLiteDialect extends Dialect {
    public SQLiteDialect() {
        super();
        ...
        ...
        ...
        registerColumnType(Types.NULL, "null");
        registerHibernateType(Types.NULL, "null");
    }
    ...
    ...
}
