            Bug ID: 296744
          Severity: crash
           Version: unspecified
          Priority: NOR
          Assignee: unassigned-bugs at kde.org
           Summary: KDE deamon crashes at login
    Classification: Unclassified
                OS: Linux
          Reporter: pedersen.magnus at gmail.com
          Hardware: Debian testing
            Status: UNCONFIRMED
         Component: kded
           Product: kdelibs

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:
Application: KDE Daemon (kdeinit4), signal: Aborted
