Hi, getting back to the error message, I remember seeing a similar error
when I failed to permit PDF output of ImageMagick.

What I did back then was this (as root):

 # cd /etc/ImageMagick-6  
 # sed -i 's+policy domain="coder" rights="none" pattern="PDF"+policy domain="coder" rights="read|write" pattern="PDF"+' policy.xml ; \

In case this resolves your issue.

        Thanks, Akira
