[pstricks] why this code does not compile

[Per Ting]

OK, this means that there is a bug in the GeoGebra pstricks
translator. But after removing the unknown character and simplifying
the equation, the following code does not yet work. What could the
reason be?

Thanks

\documentclass[11pt]{article}
\usepackage{pstricks-add}
\pagestyle{empty}
\begin{document}
\psset{xunit=5cm,yunit=1.5cm}
\begin{pspicture*}(-0.8,-1.21)(4.4,10)
\psset{xunit=5.0cm,yunit=1.5cm,algebraic=true,linewidth=0.8pt,arrowsize=3pt
2,arrowinset=0.25}
\psaxes[labelFontSize=\scriptstyle,xAxis=true,yAxis=true,Dx=0.2,Dy=0.5,ticksize=-2pt
0,subticks=2]{->}(0,0)(-0.2,-0.3)(1.1,5)[x,140] [y,-40]
\psplot[plotpoints=200]{0.0001}{0.5}{(1+x*ln(x)/ln(2)+(1-x)*ln(1-x)/ln(2)}
\end{pspicture*}
\end{document}
