bug#35591: Segfault on flatpak remote-add

[Jonathan Frederickson]

I'm attempting to use Flatpak on my Guix system, and I'm experiencing segfaults 
when attempting to add a remote repo. Provided below are the output of the 
command I'm attempting to run, as well as some info about my system.

=====
address@hidden ~$ flatpak remote-add --if-not-exists flathub 
https://flathub.org/repo/flathub.flatpakrepo

Note that the directories

'/var/lib/flatpak/exports/share'
'/home/jfred/.local/share/flatpak/exports/share'

are not in the search path set by the XDG_DATA_DIRS environment variable, so
applications installed by Flatpak may not appear on your desktop until the
session is restarted.
