Suse update applet and kdesu error

Hi all!
Today, after turning my PC on I have seen, that I have new versions of software (update applet told me).
I have clicked it to update. After it I have seen something like:
Error:… error in kdesu.cpp: no answer from deamon.
I have 11.0, KDE4.1beta
So, I had to use zypper dup in console.

I have tested kdesu (for example kdesu kate) - it works fine.
