The problem is that the directory .config/autostart/ is owned by root and not by your user. Try to change the owner with the command chown. Otherwise, launch gnome-session-properties as root and retry.
I don't think is a bug though. Regards. -- gnome-session-properties /Sessions tool/ doesn't allow to autostart programs https://launchpad.net/bugs/87607 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
