Version:            (using KDE 4.2.0)
Compiler:          GCC 4.3.3 
OS:                Linux
Installed from:    Gentoo Packages

After a power outage, Plasma crashed upon powering on the machine an logging into KDE 4.  I know that a power loss is not the responsibly of KDE, but Plasma obviously shouldn't crash just because I didn't logout of KDE cleanly.

Also, all Plasmids were gone and I had to set them up again from scratch, but that's probably another bug.

Note that a fsck was performed before logging in to KDE again and there were no errors found (Ext4).

I'm on Gentoo Linux AMD64, kernel 2.6.28.1 (gentoo-sources-2.6.28-r1).
