Description blitz.kregar 2013-04-25 21:25:16 UTC 
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.

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

OK, after reboot, issue appeared to occur again, however the backtrace appears different.

I am going to move some of my config files to a new directory and try again ( mkdir -p $HOME/plasma-config/ &&  mv $(kde4-config --localprefix)/share/config/plasma-desktop* $HOME/plasma-config/ )

Comment 2 blitz.kregar 2013-04-25 23:21:43 UTC 
After moving the config files I mentioned in last update, issue no longer occurs.  All of my desktop settings are defaulted (of course), but I can log in.
Comment 3 Martin Flöser 2013-05-30 07:24:02 UTC 
Thank you for this crash report and helping to improve our software. Unfortunately we were not able to work on this specific report yet. Nowadays the version this crash was reported against is no longer maintained and this makes it very difficult to work on this report as the source code might have changed and the information in the backtrace is no longer valid. 

Also it is quite likely that this problem got fixed in a later version. Crash reports are very often reported multiple times. 

If you are able to reproduce this crash with the latest version of KDE Plasma (4.10.3) please reopen this report and adjust the version information in the dropdown above and please also include a new backtrace as generated by the crash reporting tool. Please also make sure that the steps on how to reproduce the crash are precise and correct. Thank you!
