Comment:
Found it! In ly's `env_init` function, it tries to get the contents of the environment variable `LANG`, which might not be set (it isn't, on my system). `getenv` returns a NULL pointer in this case, and when it tries to access that pointer it segfaults. Basically what you need to do is set `LANG` to something, so it doesn't seg fault. I can report this upstream later.

You can do something like this for the service, to solve this:

```
LANG="$LANG" exec setsid ...
```
