[pstricks] Arithmetic overflow in pstricks-add

[Christoph Bersch]

Hi,

when compiling the following document, I get the error

! Arithmetic overflow.
<recently read> \pst at cntg

\listfiles
\documentclass{article}
\usepackage{filecontents}
\usepackage{pstricks-add}

\begin{document}
\begin{filecontents}{fft.dat}
0.000000 27161.972486
0.049991 0.000696
\end{filecontents}
\readdata{\data}{fft.dat}
\pstScalePoints(1,1){}{log}
\begin{psgraph}[arrows=->,Dx=0.01,ylogBase=10,Oy=-5](0,-5)(0,-5)(0.05,4.5){12cm}{6cm}
  \listplot[linecolor=red]{\data}
\end{psgraph}
\end{document}

The problem disappears, when changing the last coordinate of psgraph to
(0.07,4.5). What could be the problem?

\listfiles gives me
