Hm, all I can say: this configuration works for me.

So Guix REPL is dead after this, right?  It looks like your
"~/src/gnu/guix/emacs" is not appended to guile %load-path (it is done
in `guix-start-repl' by cons-ing `guix-load-path' to
`geiser-guile-load-path').

Could you check "C-h v guix-load-path" to be sure that its value is
really "~/src/gnu/guix/emacs".  Also just in case, show the value of
`guix-helper-file' variable.
