Application: kded4 (4.14.3)
KDE Platform Version: 4.14.3
Qt Version: 4.8.6
Operating System: Linux 3.17.4-200.fc20.x86_64 x86_64
Distribution: "Fedora release 20 (Heisenbug)"

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

I was just reading some pdf's with Okular, and had Firefox open in the background. Those were the only open applications, when the KDE Crash Reporting Assistant informed me that the KDE Daemon had crashed. Good luck finding the problem.

-- Backtrace:
Application: KDE Daemon (kded4), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
