Description of Problem:
can't change root or standard user passwd w/ kdepasswd. 

Version-Release number of selected component (if applicable):
kdeutils-2.2-2

How Reproducible:
100%

Steps to Reproduce:
1. launch kdepasswd (as root)
2. enter original passwd
3. enter identical passwords in <Password> and <Verify> fields:
   Sorry, passwords do not match <OK>
4. just to see what happens, enter original passwd in both fields:
   Conversation with 'passwd' failed. <OK>
   Information: Your password has been changed. <OK>
---
when the same steps are performed as a standard user, the utility doesn't
appear to accept the original passwd:
 Error: Conversion with 'passwd' failed. <OK>
Then it prompts you for the new passwd.... 
 Sorry: Conversion with 'passwd' failed. <OK>
 Information: Your password has been changed. <OK>
But the password is not changed in either instance.
Additionally, the following message is displayed on the terminal that is
used to launch the utility:
   passwd: Only root can specify a username

Additional Information:
what is the purpose of the --user option? The binary executes the same
way with or without it. Is the root user supposed to be able to use
kdepasswd to change standard users' passwords w/ this option? If so, 
this is broken as well:
kdepasswd & kdepasswd --user => both appear to launch the passwd utility
                                for the user that launched them.
kdepasswd veloce & kdepasswd --user veloce => both fail w/ the same error
                                even when executed as root:
                                message: "Unexpected argument 'veloce'.
                                (veloce is a standard user on my system.)
