Description of problem:
Enabling accessibility effectively locks the user out of GNOME. Once they log
out, they can't log back in unless they disable accessibility via gconftool-2.

Version-Release number of selected component (if applicable):
gnome-session-2.14.1-1.fc5.1.x86_64

How reproducible:
Always

Steps to Reproduce:
1. Create a new user
2. Login as that user
3. Enable accessibility via System->Preferences->Accessibility->Assistive
Technology Support->Enable assistive technologies
4. Logout
5. Login
  
Actual results:
"Your session only lasted less than 10 seconds..."

Expected results:
Your sessions loads normally.

Additional info:
I don't know yet if this affects other architectures.

The ~/.xsession-errors log doesn't show any error messages.
