kate is a graphical program so you should *always* use kdesu (or kdesudo if 
kdesu is broken).  It is possible to run into problems later, I have.


 From _https://help.ubuntu.com/community/RootSudo_

Graphical sudo
You should never use normal sudo to start graphical applications as root. You 
should use gksudo (kdesudo on Kubuntu) to run such programs. gksudo sets 
HOME=~root, and copies .Xauthority to a tmp directory. This prevents files in 
your home directory becoming owned by root. (AFAICT, this is all that's special 
about the environment of the started process with gksudo vs. sudo).
