Application: kded4 (4.11.2)
KDE Platform Version: 4.11.2
Qt Version: 4.8.4
Operating System: Linux 3.11.0-13-generic i686
Distribution: Ubuntu 13.10

-- Information about the crash:
- What I was doing when the application crashed: just opened the laptop. I spot a console message "firmware error" for a very short while, then the login screen showed up, I logged in and there was the Crash Reporting Assistant waiting.

Since upgrade to Kubuntu 13.10 my laptop doesn't wake up very often. Before that upgrade (on 13.04) everything was OK.

The crash can be reproduced sometimes.

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