Perhaps you didn't have a complete GNOME system, only gdm3 itself? I can
reproduce this in two ways:

* install the GNOME desktop task in a VM
* switch to tty1 and purge gdm3, gnome-core, gnome and task-gnome-desktop

and

* install the GNOME desktop task in a VM
* log in to X as a user (on tty7)
* user menu -> Switch User (moves you to tty8 with a GDM "greeter")
* switch to tty1 and purge gdm3, gnome-core, gnome and task-gnome-desktop

Not all of the "greeter" processes die when /etc/init.d/gdm3 stop is run:

default|archetype% ssh wheezy-desktop ps -U Debian-gdm -u Debian-gdm u        ~

This does seem to fix it; I've uploaded it.
