It signals

--8<---------------cut here---------------start------------->8---
split-string: Wrong type argument: stringp, nil
--8<---------------cut here---------------end--------------->8---

The issue is that

--8<---------------cut here---------------start------------->8---
(apply #'vc-git--run-command-string nil "ls-files" args)
--8<---------------cut here---------------end--------------->8---

returns nil, in project--vc-list-files.

Does this help?  Thanks.
