Seeing the same problem in Ubuntu 14.04.1 LTS.
Interestingly, the problem doesn't appear if I start gnome-do under strace:
strace -f gnome-do
Attaching strace to an already-hung gnome-do session doesn't fix it.
Running gnome-do under strace, then killing strace leaves the gnome-do session running fine:
strace -D -f gnome-do sleep 10 killall strace
Perhaps there is a race somewhere in gnome-do's startup?
