Hi Lulu, Thank you for working of this. On Wed, 14 Oct 2020 at 09:12, Lulu wrote: > I just checked this and failed to replicate it.

Could you provide the commit (hash) of the Guix you are using? Personally, I do “guix describe” and paste then the short hash (58af4c9). Then it is easier to reproduce or replicate or see if it is fixed in which version. Then, could you provide the sequence of commands you used for “replication“? And the file example you used too. It eases the process for confirming or not. :-) Thanks, simon
