Pagination Fatal Error

[eluser]Flipside Tech[/eluser]
Trying to use the pagination class for the first time and I received a PHP error.

Fatal error: Call to a member function segment() on a non-object in /webroot/_codeigniter/libraries/Pagination.php on line 136

Code:

Code:

$this->load->library('pagination');    

$this->pagination->initialize(array(
    'base_url' => base_url().'featured',
    'uri_segment' => 2,
    'total_rows' => (int)$this->caption_model->getTotalCount(),
    'per_page' => RECORDS_PER_PAGE
    ));

print_r(array(
    'base_url' => base_url().'featured',
    'uri_segment' => 2,
    'total_rows' => (int)$this->caption_model->getTotalCount(),
    'per_page' => RECORDS_PER_PAGE
    ));

echo $this->pagination->create_links();

Output:

Code:

Array (
    [base_url] => http://www.domain.com/featured
    [uri_segment] => 2
    [total_rows] => 19
    [per_page] => 15
)
Fatal error: Call to a member function segment() on a non-object in /webroot/_codeigniter/libraries/Pagination.php on line 135

What up? Any ideas?
