Errors are not related to your problem. Actually, "ox-latex.el" uses
a rather weak check to know if process was successful or not:

  (if (not (file-exists-p pdffile))
      (error (concat (format "PDF file %s wasn't produced" pdffile)
                     (when errors (concat ": " errors))))
    ...
    (message (concat "Process completed"
                     (if (not errors) "." (concat " with errors: " errors)))))

IOW, it cannot tell the difference between a successful export and an
export failure with an already existing PDFFILE.

This part needs to be improved.
