As a quick fix I changed the following line in fetch_or_compile_svg
check_output([tex_program, tex_path], cwd=working_dir)
to
check_output([tex_program, os.path.realpath(tex_path)], cwd=working_dir)

This is enough to fix the problem for me, I'm not sure if other paths should also be transformed accordingly.
