I think I finally found out why it happens :-) It looks like the 
ueberbackend is getting a little bit confused about IPV6 questions...
I compiled powerdns with verbose logging and attached the logfile to 
this mail. the setup on yavo.net is almost the same as on kos2.de (on 
the first post)...

yavo.net    SOA   <content>
yavo.net    A     <ip>
vbox.yavo.net CNAME home.yavo.net
*.yavo.net CNAME yavo.net
home.yavo.net A  <another_ip>

I think these lines are the most interesting ones...

(28) about 'home.yavo.net'

ANY of home.yavo.net

content,ttl,prio,type,domain_id,name from records where

Jan 15 11:21:29 praha pdns[18153]: UeberBackend received question for 
ANY of home.yavo.net
Jan 15 11:21:29 praha pdns[18153]: Nothing found so far for 
'home.yavo.net', do we even have authority over this domain?

there really IS a record for home.yavo.net in the database, so I don't 
know (yet) why the ueberbackend is reporting that there is none 
(although it says it's looking for ANY).
