Not necessarily. Sadly, aptitude why only discovers one reason, not
*all* reasons. More specifically, it stops its search at the first
non-automatically installed package.

Sadly, a dist-upgrade does not do a good job of keeping "automatically
installed" packages automatic. Try the following:
# aptitude markauto libdbus-1-3
$ aptitude why dbus

$ aptitude -s purge dbus
should give you that answer.

On my two headless boxes, dbus is not installed, so it is not *always*
required. But like other have said, it really depends on the services
you're running on that box.
