The problem here is that when you create an installer, the Guix inside
the image is the one defined in gnu/packages/package-management.scm
(currently 1.1.0-4.bdc801e).  Which works fine.

But when you install a system using that Guix, it will install an
_older_ Guix snapshot, from its embedded
gnu/packages/package-management.scm, which is the broken
1.1.0-3.52b01cb.

Probably we should make a new Guix snapshot to work around it.  It's a
fairly safe and easy operation, just run 'make update-guix-package' on a
commit that is available on Savannah.  Can you try it?  :-)
