I gues there's an error when parsing an IP-adress in the configure script.
The computer's IP-Adress is 10.0.0.4, /etc/hosts follows:

127.0.0.1 localhost
127.0.1.1 hgf-desktop

10.0.0.1 compi
10.0.0.2 proxy
10.0.0.3 vdr
10.0.0.4 hgf-desktop
#commenting out the line above and reconfiguring or even reinstalling the packet doesn't help
10.0.0.10 mvp

# The following lines are desirable for IPv6 capable hosts
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts

~
Obvious problem:
# debconf-communicate
get base-config/get-hostname
10 base-config/get-hostname doesn't exist

The wrong adress is directly taken from debconf, I guess.
