I could reproduce this with a chroot containing those sources:
jak@jak-x230:~$ cat /home/chroot/sid/etc/apt/sources.list
deb http://localhost:3142/debian unstable main
deb-src http://localhost:3142/debian unstable main
As well as on the main system itself:
jak@jak-x230:~$ cat /etc/apt/sources.list
deb http://ftp.de.debian.org/debian/ unstable main contrib non-free
deb-src http://ftp.de.debian.org/debian/ unstable main contrib non-free
deb http://ftp.de.debian.org/debian/ experimental main contrib non-free
deb-src http://ftp.de.debian.org/debian/ experimental main contrib non-free
deb http://people.debian.org/~jak/debian/ stable main contrib
deb http://www.deb-multimedia.org/ unstable main non-free
deb http://www.emdebian.org/debian/ unstable main

They are unmodified. The only thing relevant would be:
jak@jak-x230:~$ cat /etc/apt-cacher-ng/backends_debian
http://ftp.de.debian.org/debian/

You can access a wireshark traffic

I also attached an strace log file.
While it first does not want to start downloading dnsmasq (or at least
not send it to the [local] client), it seems to have done it sometime
later.
