no more tikz -> png génération during HTML export

["Éric Würbel" <eric.wurbel@univ-amu.fr>]

Hi list

Since my last upgrade of org (9.1.14), during HTML export, the
generation of a png image from a Tikz picture in a LaTeX src block is
not working anymore.

Here is the context :
The org-latex-pdf-process variable is set to

"latexmk -pdflatex='pdflatex -interaction nonstopmode -shell-escape' -pdf -outdir=\"%o\" -bibtex -f \"%f\""

(using customize).

Latexmk executes well, the LaTeX src block is compiled without errors,
except this little bizarre messages which appears after each execution
of LaTeX :

Output written on /tmp/babel-2628p9D//latex-26280Qa.pdf (1 page, 20872 bytes).
Transcript written on /tmp/babel-2628p9D//latex-26280Qa.log.
Latexmk: Log file says output to '/tmp/babel-2628p9D//latex-26280Qa.pdf'
Latexmk: ===For rule 'pdflatex', actual output '/tmp/babel-2628p9D//latex-26280Qa.pdf'
       ======appears not to match expected output '/tmp/babel-2628p9D/latex-26280Qa.pdf'
Latexmk: All targets (/tmp/babel-2628p9D/latex-26280Qa.pdf) are up-to-date

this double '/' is strange...

Then, when the org export process tries to convert the pdf to png with
imagemagick, there's a problem :
Converting pdffile file convert -density 150 /tmp/babel-2628p9D/latex-26280Qa.pdf -geometry 400 arbo.png...
convert-im6.q16: not authorized `/tmp/babel-2628p9D/latex-26280Qa.pdf' @ error/constitute.c/ReadImage/412.
convert-im6.q16: no images defined `arbo.png' @ error/convert.c/ConvertImageCommand/3258.

And effectively, the file /tmp/babel-2628p9D/latex-26280Qa.pdf does not
exist...

Here is the minimal org file I have built to generate this problem :

#+TITLE: Test d'export tikz qui ne marche plus

            child { node {rubrique1}
              child { node {a}}
              child { node {b}}
              child { node {c}}
            }
            child { node {rubrique2}
              child { node {d}}
              child { node {e}}
              child { node {f}}
            }
            child { node {private}}
          }
          child { node {site1}}
          child { node {site2}
            child { node {zone protégée}}
          }
          ;  
      \end{tikzpicture}
  #+END_SRC


Any idea ?
