[Tex/LaTex] Linux Libertine and pdfTeX: glyph `a’ undefined

errorsfontslibertinepdfpagespdftex

I have little doubt, usually, in the Linux Libertine font with LaTeX / pdflatex, but a couple of weeks ago, the following happened to me:
I have the file with the following test.tex

\documentclass{article} 
\usepackage[T1]{fontenc}
\usepackage{libertine}
\begin{document}
\emph{Texto de prueba enfatizado} y no \textit{enfatizado}
\end{document}

compile it without problems, but I want to make small booklets pdfpages with the following file booklet.tex

\documentclass{article}
\usepackage{pdfpages}
\begin{document}
\includepdf[pages=-]{test.pdf}
\end{document}

and compile it via pdfLaTeX, and see in .aux this line:

pdfTeX warning: pdflatex.exe (file c:/texlive/2011/texmf-dist/fonts/type1/publi
c/libertine/fxli.pfb): glyph `a' undefined

I can not see the characters in italics or emphasized, but if change to lualatex booklet.tex, it WORKS OK, why is this happening? Is it a pdfpages package problem? or is my configuration? Using TeXLive 2011 (updated) in Win XP 32 SP3.

Use in the document with pdfpages \pdfinclusioncopyfonts=1. (The source of the problem is that two fonts of libertine now have the same internal fontname, and this leads to problems).
