I have solved this problem: The source was the default overlay configuration in 
my preamble. For the slide containing the Bibliography, I changed it to <1>, 
and the duplication problem has been solved, but now I have another problem: 
all references point to one of the documents I cite. 

FTI: I use natbib andthe  authordate3 style

I tried to locate the problem by hand: 

0/ I delete AUX and bbl files (also the blg one)
1/ I pdflatex the first time: no strange errors on the logs, I get the standard 
"Package natbib Warning: Citation `XXX' on page 70 undefined on input line
 377 errors and Package natbib Warning: There were undefined citations..
The AUX file contains:
\citation{Binmore99} 
\citation{Giraud00}
\citation{Umbhauer02}
and also \bibcite{} commands for them (is this normal?)

2/ I run bibtex: no errors in the blg and the bbl contains the correct 
references
3/ I run pdflatex again: 
Now I continue to have the citation commands but all bibcite commands point to 
the same reference:
\bibcite{Binmore99}{{1}{1999}{{Binmore}}{{}}}
\bibcite{Giraud00}{{2}{1999}{{Binmore}}{{}}}
\bibcite{Umbhauer02}{{3}{1999}{{Binmore}}{{}}}

and I only get this reference in the PDF of course, instead of full reference 
set.

I am quite perplexed now about the potential origin of this problem and I am a 
rather obsessive guy :)

Have you met this problem or do you have any idea about it?

FYI information: when I switch the presentation to beamer Koma script document 
class, the references are compiled correctly.

My preamble contains (but I have been using it for some time in other 
documents, but not very recently):

\mode<presentation>
{
\usetheme{Warsaw}
\usecolortheme{lily}
\setbeamercovered{invisible}
\setbeamertemplate{navigation symbols}{}
}
\beamerdefaultoverlayspecification{<+->}
\AtBeginSection[]
{
\begin{frame}<beamer>
\frametitle{Sections :}
\tableofcontents[currentsection]
\end{frame}
}

and the slides with references and the bibliography have the overlay 
specification <1> in Lyx.
