An additional pair of parens should help as workaround.  Concretely try

    :completion-function ((lambda () (private-publish-rename-to-index 
                                            (concat private-publish-ftp-proj "guile-basics/") 
                                            "guile-basics.html")))

This works since it's possible to use a list of functions also.

I'll commit a fix against master in a second to be able to use a lambda
instead of a list containing one lambda.
