Bug 358874

Application: systemsettings (4.11.22)
KDE Platform Version: 4.14.14
Qt Version: 4.8.7
Operating System: Linux 4.4.0-smp i686
Distribution (Platform): Slackware Packages

-- Information about the crash:
- What I was doing when the application crashed:
I changed default manager from Konqueror to Dolphin, saved and changed back. After I closed the settings it crashed. I think similar crash have happened in the recent past.

-- Backtrace:
Application: System Settings (systemsettings), signal: Segmentation fault
Using host libthread_db library "/lib/libthread_db.so.1".
