Editing fails with this error:
Cannot use object of type stdClass as array in <b>D:\F_Programmierung\xampp\htdocs\core\extensions\Wikibase\lib\includes\PropertyInfoDataTypeLookup.php</b> on line <b>70</b><br />
This is caused by json_decode being called without the second parameter set in PropertyInfoTable, which causes it to return a stdClass object instead of an associative array.
