Application: kded4 (4.12.97)
KDE Platform Version: 4.12.97
Qt Version: 4.8.6
Operating System: Linux 3.13.0-22-generic x86_64
Distribution: Ubuntu Trusty Tahr (development branch)

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

kded4 crashes immediately after laptop is opened (causing resume).  Doesn't matter if battery or AC powered.  Not sure if it matters but I have it prompt me for a password everytime.

The crash can be reproduced sometimes.

-- Backtrace:
Application: KDE Daemon (kded4), signal: Segmentation fault
