What's with all these .debathena-orig.dpkg-new files?

[geofft]

On a couple of Debathena machines I use:

sipbadmin@tyger:~$ find /etc -name "*.dpkg-new" 2>/dev/null
/etc/bind/named.conf.options.debathena-orig.dpkg-new
/etc/openafs/afs.conf.debathena-orig.dpkg-new

dr-wily:~ geofft$ find /etc -name "*.dpkg-new" 2>/dev/null
/etc/bash.bashrc.debathena-orig.dpkg-new

kid-icarus:~ geofft$ find /etc -name "*.dpkg-new" 2>/dev/null
/etc/csh.cshrc.debathena-orig.dpkg-new
/etc/bash.bashrc.debathena-orig.dpkg-new

/etc/bind/named.conf.options.debathena-orig.dpkg-new
/etc/apparmor.d/usr.sbin.cupsd.debathena-orig.dpkg-new

I don't think this is supposed to be happening. Most are .debathena-orig, but all of them are touched by Debathena.
