Fresh F8 to F9 upgrade - can't start KDE - "Call to lnusertmp failed..."

This is my second upgrade from F8 to F9. This one has been a bit 
rocky, but, I seem to have stabilized things. However, I can't 
start KDE. I get a little box error that says 


"Call to lnusertmp failed (temporary directories full?). Check 
your installation."


Clicking on the 'OK' button seems to restart the xserver and 
return me to a login screen. I can log in to Gnome and XFCE. 
Created a new user and tried to login, but same result. 


I've googled this error and have followed a couple of suggestions 
such as reinvoking ownerhip of my home folder, but none of this 
has worked. 


Anyone have an idea?
