Comment 12 for bug 745011

Here is what I found out so far in a maverick chroot:

# dpkg --version
Debian `dpkg' package management program version 1.15.8.4ubuntu1 (amd64).
# dpkg --unpack /var/cache/apt/archives/udev_167-0ubuntu1_amd64.deb

# grep sbin\/udevadm /var/lib/dpkg/info/udev.md5sums

So its easy to reproduce.
