"Read more" link translation not working

To get translation working, I had to change the following code on line 129 from:

$extension .= l(t('@more_text', array('@more_text' => $settings['more_text'])), $uri['path'], array('html' => TRUE, 'attributes' => array('class' => array('more-link'))));

to:

$extension .= l(t('@more_text', array('@more_text' => t($settings['more_text']))), $uri['path'], array('html' => TRUE, 'attributes' => array('class' => array('more-link'))));
