bug#23885: SEGFAULT: In procedure char-set-contains?: Wrong type argument in position 2 (expecting character): builder for libarchive-3.1.2

[Eus]

Hi everyone!

I downloaded the Guix for USB disk, booted from it, performed the instructions 
shown at Alt+F2 but replacing "guix system init ..." with:
$ guix pull
$ guix system --fallback --keep-failed init ...

Then, I ended up with a segfault as shown below:

Any suggestion as to how to debug this?
