[kde-linux] centos 6.4 x64 can not login to kde, Could not start D-Bus. Can you Call qdbus?

hello all, just did an upgrade from 6.3. to 6.4, i found that i can not log into kde.
after selecting kde at login screen, it shows an ugly window saying
Could not start D-Bus. Can you Call qdbus?
and only one ok button, if i click it, it returns to login screen.

gnome desktop is fine though.

how can i fix it ? thanks !

the error is :

startkde: Starting up...
/usr/bin/startkde: line 283: 12207 Segmentation fault (core dumped) qdbus > /dev/null 2> /dev/null
startkde: Could not start D-Bus. Can you call qdbus?
