Looks like a bug.

I don't know if it fails for the upstream author, but I don't think
that's relevant to Guix.  More relevant I think, is that this bug
appears in Guix, so it can cause problems for Guix users, so some
fixing might be necessary.

I don't know much about Emacs though, so you might need to contact
upstream about the bug.
