Pandoc Markdown to PDF, and SVG image causing "xdvipdfmx:fatal: pdf_link_obj(): passed invalid object."?

Question

考虑以下 Markdown 文档notes.md ：

# Notes

Here some notes about including **SVG** remotely:

I have found this image:

[![Dodecahedron_schlegel](https://upload.wikimedia.org/wikipedia/commons/b/b1/Dodecahedron_schlegel.svg)](https://upload.wikimedia.org/wikipedia/commons/b/b1/Dodecahedron_schlegel.svg)

... and I'd like to have in included in the PDF via `pandoc` ...

<!-- [![RS](https://upload.wikimedia.org/wikipedia/commons/f/f2/RS-485_waveform.svg)](https://upload.wikimedia.org/wikipedia/commons/f/f2/RS-485_waveform.svg) -->

如果我尝试使用xelatex通过pandoc将其编译为 PDF ：

pandoc notes.md --pdf-engine=xelatex -o notes.pdf

一切都很好，没有错误，并且图像在 pdf 中可见：

现在，如果我取消注释第二行 - 这也是来自 wikimedia.org 的 SVG 图像的链接 - 我尝试编译，我得到大量错误，并且没有（新）PDF 生成（完整日志在 这里） ：

$ pandoc notes.md --pdf-engine=xelatex -o notes.pdf

有谁知道我该如何解决这个问题 - 所以我还可以使用 pandoc 在 PDF 中包含其他图像？

我的 latex 中的相关页面也使用了 pdf 数字。

安装 ghostscript package（我正在运行 Debian）后问题就消失了。
