This is a bug that many have fought with (myself included).  It seems to be 
linked to the wallet manager and some race conditions in it.

The best that I've come up with is a script that I run from my .kde/Autostart 
that "watches" for kded going gonzo, kills it, and restarts it via "kdedinit 

If anybody's really interested, I could post the script here...  It's a chunk 
of Python, and attempts to be somewhat general purpose, has configurable 
thresholds, etc.
