Application: plasma-desktop (0.4)
KDE Platform Version: 4.8.4 (4.8.4)
Qt Version: 4.8.2
Operating System: Linux 3.2.0-4-amd64 x86_64
Distribution: Debian GNU/Linux 7.0 (wheezy)

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

KDE is configured to autologin my user and then lock the screen.  System is installed on LVM contained inside a LUKS encrypted volume.
On startup, system logs in and locks the screen, but when I unlock it I am presented with this crash notification.

I have installed as many of the dbg packages as I could track down, but I can't seem to find which dbg packages to install for the last 2 files: /usr/bin/plasma-desktop and /usr/lib/libplasma_groupcontainment.so.4

I did expierence a similiar crash yesterday but did not take the time to review the crash info so I cannot say that this is the same.  I will update later if I can reproduce this.
