guix pull: error: Git error: invalid content-type: 'text/plain'

[divoplade]

Hello guix,

I have set up a few packages of mine at 
https://divoplade.fr/divoplade-site.git

If you clone it, it works:

git clone https://divoplade.fr/divoplade-site.git

But if I add this URL as a guix channel, I get:

guix pull: error: Git error: invalid content-type: 'text/plain'

This is the first time I get this error, as far as I remember. How do I
get this to work?

Best regards
