David Cuenca reports on mediawiki-l that a PDF from Google docs does not render on Commons. See http://thread.gmane.org/gmane.org.wikimedia.mediawiki/41507 for his message. The PDF's URL is: https://commons.wikimedia.org/wiki/File:Interproject_links_tabbed_interface_proposal_presentation.pdf Visiting a thumbnail's URL (https://upload.wikimedia.org/wikipedia/commons/thumb/3/3b/Interproject_links_tabbed_interface_proposal_presentation.pdf/page1-800px-Interproject_links_tabbed_interface_proposal_presentation.pdf.jpg) reveals the following error message: Error generating thumbnail Error creating thumbnail: convert: no decode delegate for this image format `/tmp/magick-STzEaZl6' @ error/constitute.c/ReadImage/532. convert: missing an image filename `/tmp/transform_d32a7a881ee9-1.jpg' @ error/convert.c/ConvertImageCommand/3011.

otoh, ImageMagick seemed to be ok locally when I tried convert. bawolff@Bawolff-L:~$ convert --version Version: ImageMagick 6.6.0-4 2010-11-16 Q16 http://www.imagemagick.org Copyright: Copyright (C) 1999-2010 ImageMagick Studio LLC Features: OpenMP ---- So possibly something that could be fixed on update.
I have submitted the bug to the Ghostscript bugzilla: http://bugs.ghostscript.com/show_bug.cgi?id=694536 Thanks for trying!
Upstream ticket closed as INVALID: "Please try the current version of Ghostscript and, if the problem persists, reopen the bug report."

I apologize, I should have mentioned my version of ghostscript is insanely old. I imagine the version on production is fairly old to. I guess this puts this ticket in ops territory - upgrade ghostscript and/or image magick

(In reply to comment #8) > Could you please fix this bug? Thanks, Yann See comment 6 and comment 7. Fixing the PDF file instead should be easier.
https://commons.wikimedia.org/wiki/File:Jaur%C3%A8s_-_De_la_realite_du_monde_sensible.pdf There is no problem displaying this file locally (AReader XI), so I don't understand your answer. Regards, Yann

The file in the comment above was created by printing to PDF from Google chrome on Mac. It does not strike me as a fringe issue.
