kde-4.2.2 - kded4 eating cpu cycles

[Suren Karapetyan]

Some strange issues here with kde-4.2.2 update.
After the update is done and I restart the system and login
kded4 is taking 100% on one of the CPUs.
The problem is gone on the next restart 
and doesn't come back(at least yet).
It has happened on both F10 systems I updated to 4.2.2 -
on my home desktop and laptop.
Does anyone know what can be the cause of this?
