Bug#472318: gdmgreeter pops up a "authentication failed" box before I can log in

[John Hughes]

Package: gdm
Version: 2.20.4-1
Severity: grave
Justification: renders package unusable

Can't log in because gdmgreeter pops up a "authentication failed" 
window *before* I type my login/password.  Pressing the "OK" button 
closes the window but it reappears immediately.
