Argument 3 passed to Smarty_Internal_Runtime_FilterHandler::runFilter() must be an instance of Smarty_Internal_Template, null given

[ScuzzyAyanami]

Using Smarty 3.1.29 I'm getting the following error when setting this code up in the demo folder.

Catchable fatal error: Argument 3 passed to Smarty_Internal_Runtime_FilterHandler::runFilter() must be an instance of Smarty_Internal_Template, null given, called in C:\WebRoot\smarty.3.1.29\libs\sysplugins\smarty_internal_templatecompilerbase.php on line 429 and defined in C:\WebRoot\smarty.3.1.29\libs\sysplugins\smarty_internal_runtime_filterhandler.php on line 33

I was originally on 3.1.21 and it seems like ~3.1.28 introduced this error.

Commenting/Un-Commenting out the loadFilter() call throws the error or not

demo/index.php

<?php
require '../libs/Smarty.class.php';
$smarty = new Smarty;
$smarty->force_compile = true;
$smarty->debugging = true;
$smarty->caching = false;
$smarty->cache_lifetime = 120;
$smarty->setPluginsDir(array('./plugins','../libs/plugins'));
$smarty->loadFilter('post','donothingatall');
$smarty->display('index.tpl');

<?php
function smarty_postfilter_donothingatall($compiled, Smarty_Internal_Template $template)
{
  return $compiled;

The fix is now in the master branch and will later be included in 3.1.30

Any ETA on the 3.1.30 release? This bug is causing me issues
