cmake gui can not talk to klauncher

I just install a cmake-gui , and my system is open suse 12.1.
when i click " browse source " in cmake-gui, it gives me the following error message:

kdeinit4: Communication error with launcher. Exiting!
startkdeinitlock(9594): couldn’t create slave: “Cannot talk to klauncher: Not connected to D-Bus server”

i do not know how to resolve it.

Sounds like a bug which should be reported at
