So it seems that I cannot reproduce che bug either when using guix timekmachine 
and a channel that has not been pulled by guix. I suppose in the case of 
timekmachine, it doesn't add ~/.config/guix to the search path, so the 
information is found.

Can you try pulling this channel with guix itself? You should be able to 
reproduce then.
