Setting GI_TYPELIB_PATH breaks Gnome @ Pop-OS

[Todor Kondić]

Hi all,

A $GUIX_PROFILE/etc/profile script sets GI_TYPELIB_PATH to something. On a 
hybrid (Guix+PopOS) system this prevents logging in (the "Uh Oh! ..." Gnome 
crash message).

cat /etc/os-release

Gnome version is 3.36.3



Is it fine if I unset this variable? Or, can it hold more than one paths (so if 
I figure out what is the default path on my system I can add).
