PdfHandler passes the PDF file off to GhostScript to render pages to JPEGs... if the fonts are embedded, it shouldn't have a problem unless there's a bug in GS.

Could be a production-level problem (bad version or config of GS).

Hopefully we'll be upgraded to lucid before too long...

gs rendering output of sample file first page on Ubuntu 10.04 Lucid

Here's rendering from my server that's running on Lucid.

Command line:

gs -sDEVICE=jpeg -sOutputFile=- -dFirstPage=1 -dLastPage=1 -r150 -dBATCH -dNOPAUSE -q WM_CZ_2010_Annual_Report_-_Czech.pdf > out.jpg

Appears pretty much identical to the bad output in production.
Comment 4 Sam Reed (reedy) 2011-07-19 01:09:20 UTC 
Which seems to suggest it's probably either a configuration issue, else an upstream bug...
