Re: Gnome hanging and exiting at login.

[Philippe Veber]

Turns out the culprit's not XDG_DATA_DIRS, but GI_TYPELIB_PATH. I don't see
the problem anymore if I comment the line exporting this variable in my
profile.

It seems the issue's been known for some time now:
https://issues.guix.gnu.org/35308
>From this issue it seems that there used to be a problem with both
XDG_DATA_DIRS and GI_TYPELIB_PATH, but the fact that only GI_TYPELIB_PATH
generates the problem now suggests that part of the issue has been fixed
(see maybe https://issues.guix.gnu.org/56050).

Unsetting XDG_DATA_DIRS and GI_TYPELIB_PATH in .profile like Nicolas
Goaziou suggested works for me. I still have not a clear idea what should
be done to fix the problem in a satisfying way, but I'm willing to test
suggestions.
