bug#50941: I can confirm this bug too

[jgart]

I was going to report this today but Pascal beat me to it.

I get the same error when running `guix home reconfigure file.scm`.

`guix home build file.scm` builds fine without errors.

Here's the config that I tested that with:

```
(use-modules (gnu home)
             (gnu packages) 
             ;(guixrus packages guix-easy) 
             (gnu packages bash)
             (gnu packages mail)
             (gnu packages messaging)
             (gnu packages password-utils)
             (gnu packages guile)
             (guixrus packages bower)
             (gnu packages guile-xyz)
             (gnu packages wget)
             (gnu packages version-control)
             (guixrus packages bower)
             (gnu packages emacs))

;;(define* (pkgs #:rest lst)
;;  (map specification->package+output lst))

(define-macro (define-tools group-name . group-package-names)
  "custom helper for defining groups of packages"
  `(define ,group-name
     (map (compose list specification->package+output)
          ',group-package-names)))

(define-tools jgart-profile "emacs-minimal" "offlineimap3" 
   "guile-pipe" "bower" "guile-colorized" "guile-readline" "tig"
   "git" "gajim" "gajim-omemo" "keepassxc" "wgetpaste")

(define jgart-packages
  (home-environment 
   (packages (list tig wgetpaste))))

jgart-packages
```
