I don't see nothing wrong with the above contents.
My preliminary conclusion is that there is something corrupt/wrong in/with /var/lib/pisi/index/Pardususer

Or you didn't issue the wright command to do the job..
And my manual to repair this is: (tested on my test computer)
Did you try in konsole:
sudo pisi rm Pardususer
And if ^^^ this doesn't remove Pardususer, do the next steps
1. In Dolphin go to /var/lib/pisi/index
Right-click on directory Pardususer > Root Actions > Delete
In Warning window select Continue and enter in the next window Root password + OK
Directory Pardususer should be gone from Dolphin.
2. In Dolphin goto /var/lib/pisi/info
Right-click on file repos > Root Actions > Open as text
In next sreen enter Root password + OK and wait some seconds and KWrite should open.
Select the lines with:
Edit > Cut
Save and close KWrite
Close Dolphin and repository Pardususer should be removed now.
To check open konsole and enter the following command:
pisi lr
So I am waiting for the above result of "pisi lr"

as my next
urgent advise is to also remove "Pardus-2009-test" and "PCHILFE-2009" (< doesn't exist anymore)
