Wrong use of l function in theme_username

The functions uses l as

$output = l($name, 'user/'. $object->uid, array('title' => t('View user profile.')));

while it should be

$output = l($name, 'user/'. $object->uid, array('attributes' => array('title' => t('View user profile.'))));

In order to correctly print the title attribute.

This happens twice in theme_username. I haven't checked other functions.
