The upgrade as suggested by Rob may or may not help with this bug. I advise that once you upgrade, you keep a look out for further unity-greeter crashes. I am personally unable to reproduce this bug with the upgrade, although I had a hard time reproducing it even with the version of at-spi2-core in trusty proper, so further testing is welcome.

Thanks.

Using 2.10.2 I have not had one crash, where as previously I was getting four or five crashes a week. Thank you

I've been seeing this error since I came from Unity(Ubuntu 14.04) to Gnome. I solved this problem trying this steps:

$ sudo apt-get install lightdm-gtk-greeter
$ sudo apt-get update && sudo apt-get upgrade
$ sudo reboot

Then my entire login interface changed(the options of interfaces moved to top right), but not to worry, they still there.
And the bug is gone forever =]
At least when I use Gnome, my computer is not made for Unity, too slow...

Installing the lightdm-gtk-greeter suggested by jgfenix worked for me.
Thanks!
