I know this one's a bug.

In cfrssget.php, the method used to generate the feed items for the last added media is:

function addLastAddedMedia($count,$source="") {
$results = $this->cpm->cpm_viewLastAddedMedia($count,1,$source);
$this->generateFeedFromResults($results);
}

You're calling the wrong function and passing $source as the $options argument. This code should be:

function addLastAddedMedia($count,$source="") {
$results = $this->cpm->cpm_viewLastAddedMediaFrom($source,$count,1);
$this->generateFeedFromResults($results);
}
