convert-im6.q16: not authorized `figure.pdf' @ error/constitute.c/ReadImage/420

[Karl Kastner]

Out of the blue, imagemagick stopped working for pdf:

convert figure.pdf figure.png
convert-im6.q16: not authorized `figure.pdf' @ error/constitute.c/ReadImage/420.
convert-im6.q16: no images defined `figure.png' @ error/convert.c/ConvertImageCommand/3258.

Fix: comment the following policies in /etc/ImageMagick-6/policy.xml :

  <!-- policy domain="coder" rights="none" pattern="PS" />
  <policy domain="coder" rights="none" pattern="EPS" />
  <policy domain="coder" rights="none" pattern="PDF" />
  <policy domain="coder" rights="none" pattern="XPS" /-->
