I have done another upgrade since, but I just made sure the problem
persists even there, or at least this is what happened…

  $ guix package --rollback
  switched from generation 21 to 20

  $ guix upgrade --dry-run
  The following packages would be upgraded:
     gimp               (dependencies or package changed)
     ungoogled-chromium (dependencies or package changed)
     youtube-dl         (dependencies or package changed)

  $ guix package --rollback
  switched from generation 21 to 20

…so I’m attaching the diff between generations 20 and 21 instead, with
no other changes to your command. Please find it in the file
‘guix-profile-diff.txt’, unless it got renamed along the way.
