nbconvert: Conversion to pdf fails with SVG plots in 6.0.7 (5.6.1 is ok)

After upgrading nbconvert from 5.6.1 to 6.0.7, I’m unable to convert a jupyter notebook to pdf when the notebook creates a plot using Julia’s GR.jl. This seems like it’s an issue w/ the conversion via Inkscape. My inkscape version is 0.92.4. Using the Julia Plots.jl pyplot (matplotlib) backend doesn’t seem to create this issue. I also don’t have this issue if I create a python notebook and use matplotlib to generate a pdf plot.

I don’t believe that this is #1325 since my Inkscape directory does have spaces in it

I had a similar issue while trying to convert a notebook to PDF via LaTeX in CoCalc.

Error: [NbConvertApp] Converting notebook file-1.ipynb to pdf
Traceback (most recent call last):
  File "/usr/local/lib/python3.8/dist-packages/traitlets/traitlets.py", line 528, in get
    value = obj._trait_values[self.name]
KeyError: 'command'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/usr/local/lib/python3.8/dist-packages/traitlets/traitlets.py", line 528, in get
    value = obj._trait_values[self.name]
KeyError: 'inkscape_version'

During handling of the above exception, another exception occurred:

[...]

RuntimeError: Unable to find inkscape executable --version

When I try to run ìnkscape --version, I obtain the following error (inkscape:925): Gtk-WARNING **: 13:44:30.837: cannot open display: :0.

To display the version of inkscape in a terminal, one needs to add the -z argument, i.e.

~/$ inkscape -z -V
Inkscape 0.92.5 (2060ec1f9f, 2020-04-08)

So maybe adding -z in this line https://github.com/jupyter/nbconvert/blob/f66ec517275f7c61bb5a36a5d3496ba73005d659/nbconvert/preprocessors/svg2pdf.py#L57 will fix the issues, regarding the errors above.
