Bad parsing of Command Line arguments

Description

Using: Drawing 0.8.5

If I call /usr/bin/drawing from CLI with an image as an argument , it wrongly takes the argument 0 (name of command) as the first image to open...

Steps to reproduce the bug

user$ /usr/bin/drawing tmp/screenshot_2023-12-07-10.44.png 
Error opening this file. /usr/bin/drawing isn't an image.
Traceback (most recent call last):

During handling of the above exception, another exception occurred:
