Well... at least I've figured out the problem : The gandi.net web
interface gets *very* confused if you start editing different zones at
the same time (i.e. in separate browser tabs), which is what got me to
apply configuration from another zone to the rpmfusion.org one.

So I'm currently moving away from the solution of using that as the
primary DNS server, back to one of my own servers, and 3 separate
external slaves.

If anyone notices anything weird, please reply and also CC: me so that
I see it immediately in my inbox, thanks!
