I've done some quick tests with your example block. I don't know if I'm
wrong, but I think the problem is on line 27 of `org-babel-execute:latex':

((string= "svg" extension)

I don't know if this should be considered an Org bug, but it's clear
that if the svg extension is detected in :file, the ':imagemagick yes'
option is ignored, and a type of preamble is generated that fails in
pgfsysdriver when compiling the temp tex document:

\documentclass[preview]{standalone}
\def\pgfsysdriver{pgfsys-tex4ht.def}

If I replace the above line with this conditional:

((and (string= "svg" extension) (not imagemagick))

then the imagemagick option is taken into account: it creates correctly
the pdf and then converts it to svg with 'convert' imagemagick program.
I did have to remove this line though:

#+HEADER: :imoutoptions -geometry 400 :iminoptions -density 600

otherwise, the conversion produced a dark image.

Best regards,

Juan Manuel
