Same problem here, klipper uses 100% CPU on Jaunty 64bit.
I believe I have some more information. After installing kde4libs-dbg, I get
more information about the stack when I debug the running klipper process:

What I clipped out is a a repetition of the loop involving
KConfig::reparseConfiguration() etc.
So, it looks as though a configuration file is opened repeatedly. Using
lsof, I see:

So, it looks to me, as though klipper tries to open klipperrc
repeatedly.
