Description Valentin Rusu 2008-02-17 19:11:15 UTC 
Version:           4.00.62 (using Devel)
Installed from:    Compiled sources
Compiler:          gcc (GCC) 4.1.3 20070929 (prerelease) (Ubuntu 4.1.2-16ubuntu2) 
OS:                Linux

On KUbuntu 7.10, follow these steps to reproduce the bug :
1. lock the session (CTRL+ALT+L)
2. move the mouse to bring up the unlock session dlg
3. type the correct password not to get in :)

I'm aware about the KUbuntu root password trick, so I used this :
sudo passwd root
in order to define a root password.

Please note that this is specific to this last SVN version, as last week unlocking worked.
Comment 1 Aaron J. Seigo 2008-02-18 00:26:49 UTC 
this is an installation problem. kcheckpasswd needs to be installed with root privs.
Comment 2 Valentin Rusu 2008-07-13 14:51:17 UTC 
Well, once again the screen unlocking doesn't work for me. 
I ensured kcheckpass is owned by 'root'.

I was aware of this article. So, I'll try to rebuild and find what's
wrong on my system an eventually update this.
