When opening link with gallery files like this: http://server/mod/data/view.php?id=673 PHP throws Error
Catchable fatal error: Object of class stdClass could not be converted to string in /var/www/html/moodle19/lib/moodlelib.php(5496) : eval()'d code on line 1

Solution: in Language file data.php array element $string['entrieslefttoadd'] need to replace from $a to $a->entriesleft
