Having read this bug report, it seems like the problem here is with
Nix's Emacs packaging. I therefore see nothing more to do here, and I'm
closing this bug.
If this conclusion is incorrect and this is still an issue, please reply
to this email (use "Reply to all" in your email client) and we can
reopen the bug report.
