[pstricks] pst-node psDefBoxNodes and babel french

[François Couloigner]

Hello,
this code generates (latex+dvips) a bad postscript file :

\documentclass{article}
\usepackage{pst-node}
\usepackage[french]{babel}
\begin{document}
\psDefBoxNodes{nom}{contenu}
\psdots(nom:tl)
\end{document}

Is there a knwon incompatibility between pst-node and babel with french 
option ?

PS : i  use the last version of
