Interferance between emacs-jupyter and git-commit

Hello, so I've been having some trouble with emacs-jupyter whenever magit is loaded. I finally managed to narrow it down to the git-commit package which is required by magit. When both emacs-jupyter and git-commit are loaded if I try to start up a Jupyter session in an org notebook, or via jupyter-run-repl (i've tried both python and Julia kernels), I get the following stack-trace from the debugger:

Debugger entered--Lisp error: (error "Keyword argument :coding-system not one of (:name :buffer :command :coding :noquery :stop :connection-type :filter :sentinel :stderr :file-handler)")
  signal(error ("Keyword argument :coding-system not one of (:name :buffer :command :coding :noquery :stop :connection-type :filter :sentinel :stderr :file-handler)"))

When I don't require git-commit, I do not suffer this issue.

Here's a minimal init.el to reproduce my problem:

(require 'package)
(setq package-enable-at-startup nil)

(setq package-archives
      '(("GNU ELPA"     . "https://elpa.gnu.org/packages/")
        ("MELPA Stable" . "https://stable.melpa.org/packages/")
        ("MELPA"        . "https://melpa.org/packages/"))
      package-archive-priorities
      '(("MELPA Stable" . 10)
        ("GNU ELPA"     . 5)
        ("MELPA"        . 0)))

(package-initialize)

(unless (package-installed-p 'use-package)
    (package-refresh-contents)
    (package-install 'use-package))

(eval-when-compile
  (require 'use-package))

(use-package jupyter
  :ensure t
  :config
  (require 'jupyter-julia))

(org-babel-do-load-languages
 'org-babel-load-languages
 '((emacs-lisp . t)
   (jupyter . t)))

(use-package git-commit
  :ensure t)

Commenting out the final two lines causes the problem to go away.
