I can't reliably reproduce the error myself. It simply "comes up" every
now and then if I switch between branches with an existing build and try
rebuilding Guix and rerunning the tests. Agreed, a fix would be
preferred. I have absolutely no idea how.

I don't believe the issue is limited to those two files in particular
(although it could be). That just happened to be the file causing the
problem when I caught the error and pasted it in the doc.

That makes two of us. :)
