Kicker has been crashing on me when I hover the "System" menu on KMenu. It's a Ubuntu 11.10 system, with packages from the sources available on the website.
Can anyone reproduce this? I merely installed "kubuntu-desktop-trinity". Also, this meta package should be pulling kpowersave or something that does power management.
This rings a bell from a while ago.
I think this was the bug report:

I think this is the patch:
