Setzer crashes when trying to open it.

The crash error is the following:

```

Traceback (most recent call last):

```

This crash report appears to be the same:

https://retrace.fedoraproject.org/faf/problems/bthash/?bth=aa0bb0ae60a834e7d122351834bf6acf27f931c1

The problem goes away when I install the package: python3-bibtexparser
```
Name         : python3-bibtexparser
Version      : 1.2.0
Release      : 6.fc38
```

Setzer indeed requires that packages:
```
sudo dnf repoquery --requires setzer
...
python3-bibtexparser
...
```

But it appears that it didn't get install during the update that required it for the first time. Setzer has been working fine without that package. I installed it in my system for the first time after that crash.

I think what might have happened is that python3-bibtexparser was not required for setzer but until f37 (see https://src.fedoraproject.org/rpms/setzer/blob/f36/f/setzer.spec, comp. https://src.fedoraproject.org/rpms/setzer/blob/f37/f/setzer.spec). I have been doing in place system upgrades since f34, so it looks that the upgrade from 36 to 37 didn't install the new dependencies, however, setzer didn't crash until the other day. I use it quite frequently, I would have noticed. I would say that the crash began to happen when I updated from setzer-55-1.fc38.noarch to setzer-56-1.fc38.noarch on 10 Jul 2023. Not sure if it is a problem with dnf or with setzer rpm spec.
