To address this we=E2=80=99d need an extra command-line option in =E2=80=98=
guix
download=E2=80=99 to specify the name to use in the store (similar to the
=E2=80=98file-name=E2=80=99 field in <origin>.)

So one would type:

  guix download --name=3Dfoo.tar.xz mirror://=E2=80=A6/kde-l10n-ca@valencia=
-16.12.3.tar.xz

In the meantime, you can work around it by doing something like:

  guix download -o foo.tar.xz mirror://=E2=80=A6/kde-l10n-ca@valencia-16.12=
.3.tar.xz
  guix hash foo.tar.xz

Thanks,
Ludo=E2=80=99.
