Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.3.4 (KDE 4.3.4)
Qt Version: 4.6.0
Operating System: Linux 2.6.32-gentoo-vlad i686

What I was doing when the application crashed:
I resume my machine from sleep, and error happens. I think it only happens on first suspend/resume cycle after reboot.

I have a Lacie 500GB external USB drive connected to the computer that doesn't get powered off or suspended
