SimplePie; using get_id() is giving me duplicates

Hi,
ive tried posting this on SimplePie bugs list, and SimplePie mailing list, with no help!

if someone could help me!

im processing feeds in WP using SimplePie, and keeping a note of all feeds im processing in a custom table with get_id(true); this is a mysql db with varchar(255);

$token = (string)$item->get_id(true);

but some feed items, are being processed 2 or sometimes 3 times, thereby causing duplicates.

following is the code, the function “alreadyParsed()”, is not working correctly as it should, if someone could help.

function doFeed()
{
	$url			= "http://news.google.com/news?pz=1&cf=all&ned=au&hl=en&output=rss";
	$rss			= fetch_feed($url);

	$items = 10;
	$parsed_count = 0;

	foreach ( $rss->get_items(0, $items) as $item ) {

		$link 	= esc_url(strip_tags($item->get_permalink()));
		$title	= esc_attr(strip_tags($item->get_title()));
		if ( empty($title) ) $title = __('Untitled');

		$date 	= $item->get_date('Y-m-d');
		$token 	= (string)$item->get_id(true);

		// as soon as you hit a dup, bail out //
		if(alreadyParsed($date, $token) !== false) return array($parsed_count, sprintf(__("Hit a Dup! :%s."), $title));

		// new feed, process it //
		$process_id = doItem($item);

		if($process_id > 0)
		{
			$sql = "INSERT INTO <code>&quot;. WP_INDEX_TABLE .&quot;</code> SET ";
				$sql .= " <code>process_id</code> 		= '". $process_id			. "', ";
				$sql .= " <code>process_token</code>	= '". $token			. "', ";
				$sql .= " <code>process_date</code>	= '". $date 			. "'";

			$result1 = $wpdb->query($sql);
			$parsed_count++;
			unset($sql, $result1);
		}
	}
 	unset($sql,$url);
	return array($parsed_count, __('Feeds processed'));
}

function alreadyParsed(&$date, &$token)
{
	global $wpdb;
	$sql 	= "SELECT count(*) as count FROM <code>&quot;. WP_INDEX_TABLE .&quot;</code> WHERE
			<code>process_token</code> = '" . $token		."' AND
			<code>process_date</code>  = '" . $date		."'";

	$res	= $wpdb->get_row($sql);

	if((int)$res->count > 0)
		return true;
	else
		return false;
}
