I just got the prompt again in a VM environment. The md5sum of /etc/dhcp3/dhclient-script there is a9727be0b1b5a55da5d356bf7dc0c72c.
However, this time the prompt is that dhclient needs to be restarted. Looking at the dhcp3-client.postinst script it seems like this a debconf question with high priority is always asked if it gets upgraded from lt-nl "3.0.4-2".

I will attach a debdiff with a suggested fix.
