Application: kded4 ($Id: kded.cpp 1204125 2010-12-06 11:17:10Z dfaure $)
KDE Platform Version: 4.6.00 (4.6.0)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-02063504-generic x86_64
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed:
Each time the system starts, the desktop appears.  After "wallet" password is entered and complete, the crash dialog appears.  The system seems to run normally after that except for KMix.  I must kill the KMix process as it does not respond and consumes about 10% of the processor time.

The crash can be reproduced every time.

-- Backtrace:
Application: KDE Daemon (kdeinit4), signal: Segmentation fault
