I installed emacs-debbugs
But it doesn't get autoloaded, so I had to comment out this line in my .emacs file
(add-to-list 'debbugs-gnu-all-packages "guix-patches")
because otherwise when launching emacs it claims that "debbugs-gnu-all-packages" value is void
I have to manually launch debbugs and only after that I can manipulate said variable
Not so with the Zenburn theme, though. That is available when .emacs is processed.
I know that Alex already discussed this but I can't find the email or maybe it was on the irc channel ? Sorry, I don't remember
