You might need to make sure all the packages installed correctly.
The smart package manager has a fix function, as well as a check all installed packages function.
First, update your rpm data base.... urpmi.update -a You need to be root!
This may be what you need.
To move the icons from the desktop, open konqueror in superuser-mode (file manager) select star/Tools/System Tools/File Manager Superuser -Mode.
That will require root password, from here navigate to /home/(user-name)/Desktop/
From here as root you can move things around, it might be a good idea to change the permissions for those files back to (user) while you're at it.
Hope that gets you out of trouble.
