"Can not unlock the screen" issue

Hi Guys:

Note sure if you had encountered "Can not unlock the screen, as the authentication system fails to work, You must kill kdesktop_lock(pid 7171) manually." when you try to log into Linux OS(SUSE LINUX Enterprise Server 9 (i586)). If you did, do you have a solution now? Could you please share it with me? Thanks a lot!

Have you looked in /var/log/messages? Are you sure it is a bug? Have you updated your system or reported this?

No, I havn't looked in /var/log/messages. I am not sure if this is a bug. I havn't updated my system and reported this.

After I restarted the os, it becomes workable.
