Hello list,

I finally tracked down the problem. It is not related to my use of
latexmk. It is an Imagemagick problem. The version installed by xubuntu
18.04 has a restrictive policy on pdf files. I tweaked the
'/etc/ImageMagick-6/policy.xml' file which contains the following policy
restriction :

<policy domain="coder" rights="none" pattern="PDF" />

Which I rewrote into :

<policy domain="coder" rights="read|write" pattern="PDF" />

And now everything works fine with my original code.
