Profile tokens are not replaced

When adding a link field to user profiles and using user tokens (e.g. [user:name]) to the link title, the tokens are not replaced.

I was able to get the tokens replaced by replacing:

$item['url'] = token_replace($item['url'], array('node' => $token_node));

With:

$token_user = !isset($node->nid) && isset($node->uid) ? user_load($node->uid) : NULL;
$item['url'] = token_replace($item['url'], array('node' => $token_node, 'user' => $token_user));

And replacing:

$title = filter_xss(token_replace($title, array('node' => $token_node)),
    array('b', 'br', 'code', 'em', 'i', 'img', 'span', 'strong', 'sub', 'sup', 'tt', 'u'));

With:

$token_user = !isset($node->nid) && isset($node->uid) ? user_load($node->uid) : NULL;
$title = filter_xss(token_replace($title, array('node' => $token_node, 'user' => $token_user)),
    array('b', 'br', 'code', 'em', 'i', 'img', 'span', 'strong', 'sub', 'sup', 'tt', 'u'));

Hopefully I am using the correct way to detect if you are viewing a node or a profile.
