My latest pages widget doesn't display the author anymore (the hover text now ends in 'By ').

The code of the widget is:

	function LatestPages() {
		$pages = DataObject::get('SiteTree', '', '`LastEdited` DESC', '', 5);
		$return = new DataObjectSet();
		foreach($pages as $page) {
			$versioned = Versioned::get_version("SiteTree", $page->ID, $page->Version);
			//var_dump($versioned);
			$author = Member::get_one("Member", "ID = " . (int)$versioned->AuthorID);
			//var_dump($author);
			$return->push(new ArrayData(array('Page' => $versioned, 'Author' => $author)));
		}
		return $return;
	}

var_dump($versioned); returns all items with AuthorID = 0. So I suspect something is broken there.

Anybody knows a fix so the author is again mentioned in the tooltip?
