I'm wondering what happen to my KWallet after I do the upgrade from 11.2 to 11.3 plus upgrade from KDE 4.4 to KDE 4.5?

and I got some pop-up when I launched the Choqok..

Do I need to install KWallet to fix this issue? By the way what is actually stored in the plain password? My Password? please help me guys...

here the snapshot screen..

Thanks mate..
