KDE and desktop locking

[Marcin Król]

I should wrote this a long long time ago. As I remember, when I was 
using KDE on RA, after locking desktop and entering bad password, there 
was a dialog saying "Invalid password" or something similiar. Since I'm 
on AC, after entering bad password there is a dialog too, but saying: 
"Caonnot unlock session because authentication system failed to work. 
You must kill kdesktop_lock (pid 12345) manually". This information is 
misleading, as the authentication system _did not_ failed to work. It 
_worked ok_ and checked that password was invalid. Note about manually 
killing shouldn't be there too. I suspect bad pam return value 
comparison or something, but I'm not familiar enough with kde sources to 
fix it.
