KDM -> keyboard stops responding after logout

[Marcelo Magno T. Sales]

Anyone using KDM and KDE with FC6? Here, the keyboard stops responding after a 
user logs out when using KDM. This happens most times the machine is booted, 
but not always. If it does not, the keyboard will stay functioning until the 
machine is restarted. Using GDM, this does not happen. 
But the most interesting(?) thing is that neither GDM or KDM are asking for 
the users' passwords (except for user root). Other users login without 
suppling the password (!!).
Does this happen with you? Should I file a bug?
