 --with-branch …’ leads to an invalid derivation

Hello,

The following command ends up creating an invalid derivation in the
glib-schemas hook:

--8<---------------cut here---------------start------------->8---
$ guix shell -D guile-next  --with-branch=guile-next=stable-2.2 python-matplotlib  
guix shell: error: derivation `/gnu/store/6hy95hpjbbzvppwxndzapi3f5s1xcgkm-glib-schemas.drv' has incorrect output `/gnu/store/vahx614bazd4zk5akkqp1y7aflbi1rla-glib-schemas', should be `/gnu/store/m0138ijax94m5lcdksw8jz5zdvlhdghh-glib-schemas'
$ guix describe

The problem vanishes if we pass ‘--no-grafts’ or if we remove
‘--with-branch’.

Ludo’.
