New issue by Uriel12 on void-packages repository

https://github.com/void-linux/void-packages/issues/20789

Description:
<!-- Don't request update of package. We have a script for that. https://alpha.de.repo.voidlinux.org/void-updates/void-updates.txt . However, a quality pull request may help. -->
### System

* xuname:  
  *Void 5.4.29_1 x86_64 AuthenticAMD uptodate rrrmFFFF*
* package:  
  *gnome-passwordsafe version: 3.99.2*

I did not see in the template file for gnome-passwordsafe any deviation from the upstream source.
So maybe the error messages should be filed with the upstream project.

The syntax errors mostly should be fine if my limited understanding of python3 is correct.
But maybe someone else could take a look.

### Expected behavior
Flawless install behavior.
### Actual behavior
```
