Maybe try this: add a call to $pm->pre_save() before the call to save, then echo $pm->errors if it's not empty. And also echo something if the "if ($recipients)" fails"

if ($recipients) 
{
	$pm->set_recipients($recipients, $botpermissions);
	$pm->pre_save();
	if (!count($pm->errors)) 
		$pm->save();
	else
		echo "pm errors" . explode(',', $pm->errors);
}
else
	echo "No recipients for pm";
