counsel-locate --> ivy-occur fails

[DWgit]

On emacs 27.1 from Debian 11 Bullseye, invoking counsel-locate, then invoking ivy-occur produces incorrect output in the *ivy-occur* buffer.

To reproduce:

$ git clone https://github.com/abo-abo/swiper/
$ cd swiper
$ make plain

1. M-x counsel-locate
2. Enter search string. Here using update-motd.d, which has 3 hits on my system. The failure seems to happen regardless of query.
3. (wait for locate to finish)
4. C-c C-o

The resulting *ivy-occur* buffer contains only:

2 candidates:
    
    working...

(setq debug-on-error t) does not affect the behavior.
