I have the line (setq org-image-actual-width '(600)) in my init file. With all versions of ImageMagick till 6.9.9-13 it worked well, means scaling inline images to 600 px in width.

But with all higher versions (now it is 6.9.9-17) scaling not happens with the error `ImageMagick error: no decode delegate for this image format `JPEG' @ error/constitute.c/ReadImage/504`.

Is something can be done in the org-mode or it is imagemagick bug?
