failing with Gio::Error

[dja001]

Hi @dmitry-t,

I am encountering a new problem with the extension. I am unsure if its related to a new version of inkscape or my linux distro. When I try to run the extension on any file, I get an obscur Gio::Error and the error message that I am pasting below.

The weird thing is that if I try to run the failing conversion command from a small local python script:

import subprocess
cmd = ['inkscape', 'intro.svg', '--export-area-page', '--export-type', 'pdf', '--export-filename', '    test_intro.pdf']
subprocess.run(cmd, check=True)

There is no problem and the conversion runs like charm.

Versions:
inkscape-export-layers v3.3.2
Inkscape 1.3 from PPA
Linux Mint cinnamon 20.2 Uma

Error traceback:
Note that towards the bottom, there is also an error with the way the traceback is handled but that is not the primary problem that concerns me here.

I can run further tests if that can help you finding the problem.

Thanks!

I'd like to add that I encounter exactly the same issue with the same error messages.

After some googling I found a related issue in inkscape's gitlab and figured out a way to make it work for me through a very simple hack (see the pull request).
