Check if your file is saved with UTF-8 BOM, if it is, just remove it. — Dejan Marjanović, Oct 18 '11 at 00:31

You have extraneous whitespace after the ?>, remove the last line.

Do you use 1.7.2 version of CodeIgniter? Please modified your code:

find

header("Content-Type: application/rss+xml");
view('rss/feed', $data);

replace with:

$this->output->set_header("Content-Type: application/rss+xml");
$this->load->view('rss/feed', $data));
