In 1.16.x there is a small error in includes/diff/DifferenceInterface.php. In svn/trunk, it has been moved to includes/diff/DifferenceEngine.php :

In function generateDiffBody( $otext, $ntext ) {...}

There is:

return $wgContLang->unsegementForDiff( wikidiff_do_diff( $otext, $ntext, 2 ) ) .	$this->debug( 'wikidiff1' );

I guess it ought to be:

return $wgContLang->unsegmentForDiff( wikidiff_do_diff( $otext, $ntext, 2 ) ) .
			$this->debug( 'wikidiff1' );
