A strange pdf export problem

[Alan Schmitt]

Hello,

I've just noticed a strange pdf export issue that only occurs under  
some very specific circumstances, namely using tikz (which is a  
picture library for latex-beamer). According to the tikz and beamer  
developer, the problem is with OmniGraffle. Here is what the  
developer (Till Tantau) says:

Now here is the precise problem. Using the  OmniGraffle file http:// 
sardes.inrialpes.fr/~aschmitt/alignment1.graffle, exported as pdf  
(http://sardes.inrialpes.fr/~aschmitt/alignment1.pdf), the following  
latex code:

\documentclass[t]{beamer}

\usepackage{tikz}

\begin{document}

\begin{frame}
         \pgfimage[width=6cm]{alignment1}

         \tikz\node{\pgfimage[width=6cm]{alignment1}};
\end{frame}

\end{document}

compiled with pdflatex results in the output http:// 
sardes.inrialpes.fr/~aschmitt/bug.pdf, where the second picture has  
lines of incorrect size.)

I'm using OmniGraffle pro 4.0. Strangely enough, the pdf looks fine  
when using Preview.

Could this be a pdf export bug?

Thanks a lot,

Alan
