_From guesstimating, the issue is that `/var/log/journal/db71213e586c4af39cc6e668d6f96fd6/user-1001.journal` does not exist anymore. Idk why would that be "so severe" as to core out._

Description: Ubuntu 20.04.6 LTS
Release: 20.04
```
I am aware that this is an old version. OTOH, "even trying to make gdb spit this out for me" took a solid calendar week. Building (also for an Debian) sounds like a nightmare.
I hope I don't have to re-start a new database for this.
I would also hope that future versions would have some more logging, so that people don't need to torture themselves trying to get `aide` to talk to them 😕
