New issue by streaksu on void-packages repository

https://github.com/void-linux/void-packages/issues/16401

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 5.3.10_1 x86_64 AuthenticAMD uptodate rF`
* package:  
`gnome-boxes-3.32.1_1`

### Expected behavior
Starting up properly, both when pressed in the GNOME app menu and command line.
### Actual behavior
When pressing the icon in the app menu the app pops up to then die shortly, running it in command line highlights a segmentation fault, this is the output of `gnome-boxes`:
```
(gnome-boxes:2173): Gtk-WARNING **: 04:13:04.003: GtkFlowBox with a model will ignore sort and filter functions

(gnome-boxes:2173): Gtk-WARNING **: 04:13:04.004: GtkListBox with a model will ignore sort and filter functions

(gnome-boxes:2173): Boxes-WARNING **: 04:13:04.360: libvirt-broker.vala:66: Failed to update domain 'voidlinux-2': Failed to set domain configuration: XML error: Invalid PCI address 0000:04:00.0. slot must be >= 1

(gnome-boxes:2173): Boxes-CRITICAL **: 04:13:04.360: boxes_vm_importer_get_source_media: assertion 'self != NULL' failed
Segmentation fault
```
Note that this is both in wayland and Xorg.

### Steps to reproduce the behavior
Simply running the program, both from command line and graphical tools.
