Bug description:  Incorrect error when setting PDO::ATTR_STATEMENT_CLASS with ctor_args

Description:
------------
I'm getting the following error when the ATTR_STATEMENT_CLASS option is
set...

Fatal error: Uncaught exception 'PDOException' with message
'SQLSTATE[HY000]: General error: PDO::ATTR_STATEMENT_CLASS requires format
array(classname, array(ctor_args)); the classname must be a string
specifying an existing class' in
..../drupal7/includes/database/database.inc:338

The same configuration works for PHP 5.2 and 5.3

The reproduce code is the constructor of the DatabaseConnection class of
Drupal 7, see also
http://cvs.drupal.org/viewvc.py/drupal/drupal/includes/database/database.inc?revision=1.57&view=markup

Reproduce code:
---------------
  function __construct($dsn, $username, $password, $driver_options =
array()) {
    // Because the other methods don't seem to work right.
    $driver_options[PDO::ATTR_ERRMODE] = PDO::ERRMODE_EXCEPTION;

    // Call PDO::__construct and PDO::setAttribute.
    parent::__construct($dsn, $username, $password, $driver_options);

    // Set a specific PDOStatement class if the driver requires that.
    if (!empty($this->statementClass)) {
      $this->setAttribute(PDO::ATTR_STATEMENT_CLASS,
array($this->statementClass, array($this)));
    }
  }


Expected result:
----------------
The connection can be established....

Actual result:
--------------
Fatal error: Uncaught exception 'PDOException' with message
'SQLSTATE[HY000]: General error: PDO::ATTR_STATEMENT_CLASS requires format
array(classname, array(ctor_args)); the classname must be a string
specifying an existing class' in
