bug#23389: segfault for non-root user

[Myles English]

Hello,

Just installed binary x86-64 nix on Arch Linux as per instructions here:

http://www.gnu.org/software/guix/manual/guix.html#Binary-Installation

The install for root when well and the hello sample package installed
fine.  Then I went to setup my user as described here:

http://www.gnu.org/software/guix/manual/guix.html#Application-Setup

but got a segfault at:

$ guix package -i glibc-locales

and in fact even just

$ guix

I don't know if this backtrace is useful but here it it:
