Bug 335114

Application: kded4 (4.13.1)
KDE Platform Version: 4.13.1
Qt Version: 4.8.6
Operating System: Linux 3.14.2-200.fc20.i686+PAE i686
Distribution: "Fedora release 20 (Heisenbug)"

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

A popup saying "modem lost ip settings" appeared before kded4 crashed. Don't know if it is related to it much, however nothing else strange happened.

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