Panels integration fails for custom fields and formatters

I just tested to use Panels with some custom fields and formatters created with cck-hooks (cck gmapfield and cck nodemenu). But both didn't work propperly, because in both cases wrong or no formatter was called, due to:
$node_field[$delta]['view'] = content_format($field, $item, $conf['formatter'], $node);
in content_panels.inc on line 126

$conf['formatter'] does not exists, instead use $formatter:
$node_field[$delta]['view'] = content_format($field, $item, $formatter, $node);
in content_panels.inc on line 126

This little patch is attached:
