I now know what is happening. I had a large build system that failed if /bin/sh pointed to dash so I set it to point to /bin/bash instead. That is what makes the login fail. starting xinit then "/etc/gdm/Xsession gnome-session" produces the following error
/etc/gdm/Xsession: Beginning session setup...
/etc/bash_completion.d/apport_completion: line 128: `_apport-bug': not a valid identifier
setting back the /bin/sh link to dash makes it work and I can also login from the normal gdm login screen.
So this bug should be moved to apport or maybe bash ?? but I do not know how to do that
