The folowing example does not compile :

\documentclass{article}
\usepackage[francais]{babel}
\usepackage{tikz}
\usetikzlibrary{trees}

\begin{document}


\tikzstyle{level 1}=[level distance=2.5cm, sibling distance=2.5cm]
\tikzstyle{level 2}=[level distance=2.5cm, sibling distance=2cm]
\tikzstyle{bag} = [text width=3em, text centered]

\begin{tikzpicture}[grow=right]
\node[bag] {A}
    child {
        node[bag] {$ B $}        
        child {
                node[bag, label=right:
                    {$C$}] {}
            }
    };
\end{tikzpicture}

\end{document}

If I don't load babel (with the francais option), everything runs
smoothly. If I change it slightly :

\documentclass{article}
\usepackage[francais]{babel}
\usepackage{tikz}
\usetikzlibrary{trees}

\begin{document}


\tikzstyle{level 1}=[level distance=2.5cm, sibling distance=2.5cm]
\tikzstyle{level 2}=[level distance=2.5cm, sibling distance=2cm]
\tikzstyle{bag} = [text width=3em, text centered]

\begin{tikzpicture}[grow=right]
\node[bag] {A}
    child {
        node[bag] {$ B $}        
        child {
                node[bag]{$C$}
            }
    };
\end{tikzpicture}

\end{document}

everything runs smoothly again. Quite strange, isn't it ?

Copy on both fr.comp.text.tex and comp.text.tex, and sent to Daniel
Flipo (the maintainer of the french babel module), followup to
fr.comp.text.tex (but if you answer in english, please answer on
comp.text.tex).

En fran�ais dans le texte : le premier exemple ne compile pas lorsque
j'utilise babel, avec l'option fran�ais. Si on change les labels
(deuxi�me exemple), tout fonctionne correctement. Bug bizarre...

Copie envoy�e � Daniel Flippo (qui maintient le module francais de
babel). Merci de faire suivre sur comp.text.tex si vous r�pondez en
anglais, sinon, suivi sur fr.comp.text.tex.
