The bug occurs when dpkg tries to install libc6 deb, and this triggers the telinit command.
As you are adamant that this bug is unrelated to the several bugs that are already filed which describe this exact problem, I've decided not to spend any more time on it.
If you wish to investigate the issue yourself, then I recommend you install 13.10 on a system and upgrate it with do-release-upgrade.
