Empty store items

[Thorsten Wilms]

Hi!

I wanted to try use lv2ls and lv2info, both belonging to lilv and found
the commands to do nothing, have no man page and no --help. Then I
tried to start Ardour, but it fails with:

```
WARNING: Could not check your glib-2.0 for mutex locking atomic
operations.

/gnu/store/yxivqfaqiaihycfpzrk5pil6p4x5s4j2-ardour-6.6/lib/ardour6/ardour-6.6.0:

/gnu/store/5q75cw8lnw4kfg9nss5vwkx8pxakk96l-lilv-0.24.10/lib/liblilv-0.so.
0: file too short
```

That store item has size zero, indeed.

I tried:

```
$: sudo guix build --repair lilv
path `/gnu/store/5q75cw8lnw4kfg9nss5vwkx8pxakk96l-lilv-0.24.10' is

But the problem persists. All actual lilv store items remain empty.


gc --verify thinks the store is in order, so there’s nothing to repair:

```
sudo guix gc --verify=repair
reading the store...
checking path existence...
```

There are 7694 empty items, even after `guix package
--delete-generations; guix gc --collect-garbage`:

```
$: /gnu/store: find -empty | wc -l
7694
```

I had trouble with fs corruption before, but this always meant being
thrown into the initramfs prompt for a round of fsck. Didn’t happen
this time, and fsck did not find any issues now.

There is 39G free disk space and inode use is at 18%.

Any ideas?
