pypi URL 404

[Jack Hill]

Hi Guix,

I've created the following package definition using the pypi importer. 
However, when I try to build it with guix build -f … the build fails 
because it cannot download the source. The downloader gets redirected to a 
url that returns 404. However, the pypi importer was able download the 
source.

Package definition produced by the importer:

(define-module (ducktype)
  #:use-module ((guix licenses) #:prefix license:)
  #:use-module (guix packages)
  #:use-module (guix download)
  #:use-module (guix build-system python))

(package
  (name "python-mallard-ducktype")
  (version "1.0.1")
  (source
    (origin
      (method url-fetch)
      (uri (pypi-uri "mallard-ducktype" version))
      (sha256
        (base32
          "04mjj8apzm0cb4vk73vydgfiw8cyznfy3zrb99xs9d2k8x7cxc99"))))
  (build-system python-build-system)
  (home-page "")
