Comment 7 for bug 1110580

Just did the second reboot since your solution. I had the expected login-screen. So far so good.

But I had a look at the syslog:

Jan 31 21:59:58 emachine gdm-simple-greeter[1789]: Gtk-WARNING: Overriding tab label for notebook

Jan 31 21:59:58 emachine gdm-simple-greeter[1789]: CRITICAL: get_column_number: assertion `i < gtk_tree_view_get_n_columns (treeview)' failed

Would this mean the problem still exists?

I attach the newest syslog.
