I found the reason for this behavior. It is a bug in teh upstart script
/etc/init/gdm.conf
Inside the script there is a test which dm should be started. If not gdm
it exits, but it exits with EXIT_STATUS=1, which then triggers the start
of the failsafe session.
I append a patch for gdm.conf
Here is the companion patch for /etc/init/kdm.conf

Since failsafe-x was enabled in karmic it starts if gdm is disabled and kdm
is used. (low graphics
