There must be some misunderstanding, I was using maradns as a recursive 
solver, not on my own zone. I tried on my own zones, and it was 
correctly working :)

Then I played a bit, and found that sometimes djbns and bind recursive 
servers also lost some records with an ANY lookup...

Ok, so it wasn't bug, I just learned something new about the DNS protocol.
