Oops, that means I was too hasty with my commit.
Should I revert the change then? Do you see any problems?

About dpkg losing track of the md5sum:
In case dbus-1-utils is purged, it shouldn't be an issue, as the
conffile would be removed in this case anyway, right?

The only problem I can see is, that dbus Replaces dbus-1-utils. So the
conffile can change ownership and move from the dbus-1-utils to the dbus
package (in which case the PKGNAME would be wrong).
This case can only happen though, when rm_conffile in dbus.preinst was
added after the Replaces.

Why is it that all of the instruments seeking intelligent life in the
universe are pointed away from Earth?
