The bug here is that it picked the system-wide database:

  openat(AT_FDCWD, "/var/cache/guix/locate/db.sqlite", 
O_RDONLY|O_NOFOLLOW|O_CLOEXEC) = 14

but later decided that it was too old and that it needed to be
refreshed.  But of course, that file is read-only for unprivileged
users.

There’s a bug in the file-choosing logic.

To be continued…
