Application: kmixctrl (4.3)
KDE Platform Version: 4.9.80
Qt Version: 4.8.4
Operating System: Linux 3.7.0-0-generic i686
Distribution: Ubuntu Raring Ringtail (development branch)

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

after a recent update of project neon (specifically project-neon-kmix and project-neon-kmix-dbg packages), kmix crashes right after reboot and kded (kdeinit4) does not start
 (KDE Daemon/Kmix/KmixCtrl)

also three dr. konqi windows appear - one for kde daemon, one for kmix and one for kmixctrl.

when i try to send the dr. konqi report after inputing my username/pw i get error 
failed to communicate with kded

i have to initiate the comman kdeinit4 in konsole so i can send the report

i use kubuntu raring all newest stuff in project neon.

nice day
and thank you for all help...you are all the best!

Simon :)

The crash can be reproduced every time.
