[pstricks] Lualatex and auto-pst-pdf

[Peter Breitfeld]

I have the following file, named luatest.tex:

\documentclass{article}

\usepackage{fontspec}
\setmainfont{TeX Gyre Pagella}

\usepackage{pstricks}
\usepackage{auto-pst-pdf}

\begin{document}

\paragraph{Hier ein pstricks-Bild}
\begin{pspicture}(5,3)
  \pspolygon[fillstyle=vlines](0,0)(5,3)(3,0)
\end{pspicture}

\end{document}

When I try to compile this using:

luatex -shell-escape luatex

I get the following warnings and the pspolygon is not drawn:

-------------------------------------------------

(pst-pdf)                ps2pdf luatest-pics.ps
(pst-pdf)                ---------------------------------------------------- .


What are the right settings please?
