bug#34616: neovim segfaults

[Julien Lepiller]

Hi,

I've updated to the latest guix and upgraded my neovim package. 
Unfortunately, it segfaults:

$ nvim
Erreur de segmentation (core dumped)

Here is my current guix:

Génération 34   22 févr. 2019 14:01:39  (actuelle)
  guix 28cbf65
    URL du dépôt : https://git.savannah.gnu.org/git/guix.git
    branche: master
    commit : 28cbf65cb944606aafc8b07edd2c521ca58c3127

GUIX_PACKAGE_PATH="/home/tyreunom/nosave/guix-more"

I'm not sure how to debug that, so I'd appreciate some help here :)
