Guile-GI: builder:new-from-file: Segmentation fault

Hi,

I'm trying to learn some Guile-GI, but I just hit a segfault. I was trying to create a GTK Builder from a file:

I don't have a GitHub account (https://github.com/spk121/guile-gi), so I'm reporting here instead.

This is the UI file I used: https://luis-felipe.gitlab.io/downloads/temp/app.ui.

I'm on Guix System, using guile-gi 0.3.1.
