"sort_asc" does not exist in "/namespace.html.twig"

[silentFred]

Getting this with a fresh composer installed phpDocumentor:

[Twig_Error_Syntax]
The filter "sort_asc" does not exist in "/namespace.html.twig" at line 24

Running windows 8 with PHP 5.3.26. I'm guessing it's a php version issue?

It happens here when using the "clean" template, not with the "responsive" template. phpDocumentor loaded with composer;
phpDocumentor 2.2.0
template-clean 1.0.6
twig/twig dev-master (ae72b5d)
