select() + withColumn() query error after upgrading to version 1.6.8

[nibsirahsieu]

before upgrading to version 1.6.8, the following query runs fine:

   $c = new ModelCriteria('bookstore', 'Author');
   $c->join('Book');
   $c->withColumn('COUNT(Book.Id)', 'nbBooks');
   $c->select(array('FirstName', 'LastName'));
   $rows = $c->find();

but, after upgrading to version 1.6.8, i have to include the nbBooks column into the array select(), for example:

   $c = new ModelCriteria('bookstore', 'Author');
   $c->join('Book');
   $c->withColumn('COUNT(Book.Id)', 'nbBooks');
   $c->select(array('FirstName', 'LastName', 'nbBooks'));
   $rows = $c->find();

after tracking down the source code, the error occurs because variable $this->asColumns is resetted by this code.
If i comment out that code, my code work fine, but this test will fail.
