Something is decidedly broken in the UeberBackend indeed - I've seen this
myself with different backends. I'll probably be able to really fix this

You can't get them out, unless you edit Makefile.am. The bindbackend can't
be removed completely I think.

Can you try 'echo 0x80b62be | addr2line -e /usr/sbin/pdns_server' and send
me the output?

Very good & consistent trace, much appreciated. Will help me solve things
more quickly.
