Application: plasma-desktop (0.4)
KDE Platform Version: 4.10.1
Qt Version: 4.8.4
Operating System: Linux 3.8.4-202.fc18.x86_64 x86_64
Distribution: "Fedora release 18 (Spherical Cow)"

-- Information about the crash:
- What I was doing when the application crashed:

Started up the laptop.

Booting in to KDE, before the desktop properly appears, I receive a message along the lines of the power management couldn't find any modules... or something...

Then the crash dialog comes up

-- Backtrace:
Application: Plasma Desktop Shell (plasma-desktop), signal: Segmentation fault
