The daemon used in the test, or the daemon used to do the package build?

I ran it again, and I've got the same error:

actual-error:
+ (srfi-34
+   #<condition &nix-protocol-error [message: "path `dtmp/guix-tests/store/462z3fnl7bs44vp9s97jyg1z74nsfvly-tar' is not in the Nix store" status: 1] 1754ed0>)

So that's either a very funny coincidence, or it's a structural problem.

Ok.  That's some good news at least. :)

Do you have any suggestions for how I can debug this problem?

Kind regards,
