To reproduce:
Login to GNOME on a xxxxx ray server.
Unset the Desktop->Preferences->Accessibility->Assistive technology support preference
makesure the GTK_MODULES environment variable isn't set to force loading of accessibility modules.
Log out and log back in.
ps -efl | grep at-spi-registryd | grep {your login id}
If this daemon exists, kill it (pkill at-spi-registry) or kill by the PID returned by the grep.
ps -efl | grep at-spi-registryd | grep {your login id}
When you are sure that your registryd is not running, pull out your xxxxx ray smart card and reinsert it.
The at-spi-registry daemon will start, even though accessible device support is specifically disabled:
bash-3.00$ ps -efl | grep -i at-spi-registryd | grep -i bn128650
0 S bn128650 116 1 0 40 20 ? 7089 ? 16:06:13 ? 0:04 /usr/lib/at-spi-registryd --oaf-act
