seams the solution is very easy:
class News extends \Tx_News_Domain_Model_News {
                    ^ just this slash

but now the configuration is messed up somewhere else.
As the extension_builder created a new record variant which was not 
intended I had to clear/clean a lot of EB-code inspired by [1].
Maybe I cleared too much, or defined too less:

Fatal error: Call to a member function rewind() on a non-object in 
/var/www/typo3temp/Cache/Code/cache_phpcode/Domain_Model_News.php on 
line 460

this seams to be the full code of the News-Class
001 <?php
002 /***********************************************************************
003 	this is partial from: 
/var/www/v61/typo3conf/ext/news/Classes/Domain/Model/News.php
004 ***********************************************************************/
:
028 /**
029  * News model
030  *
031  * @package TYPO3
032  * @subpackage tx_news
033  */
034 class Tx_News_Domain_Model_News extends 
Tx_Extbase_DomainObject_AbstractEntity {
:
453	/**
454	 * Get first category
455	 *
456	 * @return Tx_News_Domain_Model_Category
457	 */
458	public function getFirstCategory() {
459		$categories = $this->getCategories();
460		$categories->rewind();
461
462		return $categories->current();
463	}

as I have not touched anything about categories: what is missing?
