unity-greeter crashed with SIGSEGV in g_idle_dispatch()

[sanmiguel9]

I added a new user with the graphical tool "System Settings --> User Accounts".
Then I encrypted its home directory with

$ sudo ecryptfs-migrate-home -u USER

This migration finished successfully, and I was adviced to login with the new user before reboot. However when I logged out, unity-greeter went crazy and crashed after 2-3 seconds, started itself again, crashed, etc. After a reboot the same thing happened. I had to remove the new user account in a virtual terminal (Ctrl-Alt-F1) with

$ sudo deluser USER

After that, unity-greeter worked normally
