Application: kded4 ($Id$)
KDE Platform Version: 4.7.4 (4.7.4)
Qt Version: 4.7.4
Operating System: Linux 3.2.0-2-amd64 x86_64
Distribution: Debian GNU/Linux testing (wheezy)

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

A normal login, have tried different settings in kmix (save volume on/off). but i still get the crash each time i login.

I'm not sure it is kmix related, but that seems to be the only solutions given in the other posts.

The crash can be reproduced every time.

-- Backtrace:
