dpkg -S segfaults on squeeze

Thanks for the great project!

```
❯ docker run -ti --platform linux/amd64 debian/eol:squeeze bash
root@abdbe178198a:/# dpkg -S foo
qemu: uncaught target signal 11 (Segmentation fault) - core dumped
Segmentation fault
```

This is on an arm64 machine, so it is using qemu, but the same happens on an x86_64 macbook as well. 

I wonder if anyone has seen this.
