Bug 457836

Description of problem:

Since I upgraded to Fedora core 9, and from teTeX (using pdftex version 1.21a) to texlive (using pdftex version 1.40.3 with poppler), the beamer presentations are not being rendered correctly any more.

When using rounded and shadowed blocks in a presentation, the plain text
and text in description environments gets represented in grey instead of
black. This happens only if a block environment is present, and affects
all text after that block environment (even on following frames).

Has been tested on another system using pdftex 1.40.x without libpoppler and did not show the problems presented here.

How reproducible:

always.

Steps to Reproduce:
1. Create a file with the following content:
**********************************************************************
\documentclass{beamer}

\mode<presentation>
{
  \usetheme{Darmstadt}
}

\begin{document}

 \begin{frame}
 \frametitle{Testing}

\begin{description}
\item[Black] This text gets displayed OK.
\end{description}

Plain text also works OK here.

\begin{block}{Test 1}
\begin{description}
\item[Black] This text gets displayed black.
\end{description}
\end{block}

\begin{description}
\item[Gray] This text gets displayed gray, but should be black.
\end{description}

Plain text also is affected.

\begin{itemize}
 \item This works well, though.
\end{itemize}

\begin{enumerate}
 \item Ditto.
\end{enumerate}

\end{frame}


\end{document}
**********************************************************************
2. Run pdflatex or latex on the file
3. View the result
4. Compare with results of the same file on Fedora core 8 with teTeX, or on RHEL 5.2.
  
Actual results:

Specific areas are displayed in gray (shaded out) instead of main color.

Expected results:
