tex file for reproducing bug
I noticed when printing a PDF file produced with latex that certain characters are printed on top of each other when printing from Evince. This can be reproduced in the following way:
1. Run "pdflatex aa.tex"
2. Run "pdftocairo -pdf aa.pdf cc.pdf"
3. Notice that the output cc.pdf contains overprinted characters when viewed on screen, whereas aa.pdf looks fine.
This is with poppler version 0.20.4, cairo version 1.12.2 and pdflatex from TexLive 2012.

From the result it looks like the width of the embedded beta character is wrong. Note that all other cairo output devices (tested ps, svg, x11) work fine for me.
An even simple test document is to just put two beta characters in the document. You can see then, that the beta character still does have a width, but it is much too small.
Setting as "not our bug" since it was actually a bug in cairo, note that as per Adrian's comment it is been already fixed in cairo upstream

I changed the product to cairo at the same time as I pushed a fix.
