biblatex: per chapter and per section bibliography [closed]

Question

I'm using biblatex for PhD thesis.

I want to have per chapter bibliographies. Moreover I would like to split the bibliography for each \section. Therefore I use refsection=section when loading biblatex and use \bibbysection[heading=subbibliography] to print the references.

The problem is all list of references have the same title (References). I would like to use the number of the \section (or even better the name).

I have found the way to do that in the manual (section 3.10.3) but can't make it work. For instance with the following file:

\documentclass[12pt,a4paper]{scrbook}
\usepackage{csquotes}
\usepackage[backend=biber,backref=true,hyperref=true,%
        refsection=section,%
        firstinits=true,%
        style=alphabetic,%
        indexing=true,%sortcites=true
        url=false,doi=false]{biblatex}

\defbibheading{subbibliography}{%
\section*{References from section \ref{refsection:\therefsection}}}
% \usepackage{nameref}
% \defbibheading{subbibliography}{%
% \section*{\nameref{refsection:\therefsection}}}
\bibliography{test}
\begin{document}

\chapter{Yep}

\section{My first method}

See~\cite{Dubois2010}.

\section{My better method}

See~\cite{Dubois2011}.

\printbibheading
\bibbysection[heading=subbibliography]

\end{document}

And the bib:

@INPROCEEDINGS{Dubois2011,
author = {Dubois, Mathieu},
title = {New stuff},
year  = {2011}
}
@INPROCEEDINGS{Dubois2010,
author = {Dubois, Mathieu},
title = {Old stuff},
year  = {2010}
}

I get:

Bibliography
References from section 1
...
References from section 1.1

Where I expected:

Bibliography
References from section 1.1
...
References from section 1.2

Any idea? ...

I'm using TeXLive 2010 on Ubuntu 11.04 (biblatex version 1.4c).
