Subject: broken guix time-machine + software-heritage
Date: Mon, 03 Apr 2023 23:39:32 +0200

Hi Guix!

I was trying to use guix time-machine as I did in the past, but the
recent updates with software heritage seem to have broken my use of it.

Here's the channels.scm file I used:

(list (channel
        (name 'guix)
        (url "/https://git.savannah.gnu.org/git/guix.git")
        (commit "1984d56b0e437af7be7fa6cf8e1a00e45eb8ffa1")
        (introduction
          (make-channel-introduction
            "9edb3f66fd807b096b48283debdcddccfea34bad"
            (openpgp-fingerprint
              "BBB0 2DDF 2CEA F6A8 0D1D  E643 A2A0 6DF2 A33A 54FA")))))

Here is the content + backtrace of the time-machine call, after the ~10
hours long object processing on Software Heritage side:
