The same bug has been present in GNOME on GuixSD since the beginning of our GNOME support. I can confirm that it's 100% reproducible on my GuixSD system, and as I recall it's been confirmed by David Thompson and Andy Wingo at least. > Mohammed, do you think this could be Guix-specific?

I would guess that our unusual filesystem layout prevents GNOME Shell from finding something that it's looking for, and that the error handling in that case is deficient or non-existent. In case anyone missed it, Thomas Danckaert recently made a significant contribution to discovering the cause of this bug, and provided a workaround: https://bugs.gnu.org/24445#8 Given this, I suspect that it would not take long for a motivated developer to complete the investigation and fix this bug properly.
