omg KDE4 is really not cool!

[Nicholas Yau]

I have been using kde for many years, this version is really giving a 
lot of trouble in the release.

when i am trying to set something in the system setting, in appearance 
or in desktop section, after i set something there,  logout and try to 
login again, i will not be able to do so.

the plasma system tray icon is really a mess, cannot auto reduce by 
itself. this version is really a memory hunger, slow respond compare to 
fedora 8.

anyone who noticed please help.
