Bug 360464

Qt Version: 5.5.1
Operating System: Linux 4.4.3-300.fc23.x86_64 x86_64
Distribution (Platform): Fedora RPMs

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

started settings
typed "windows" to filter the icon list
clicked on on of the hilighted icons
then I think it crashed

-- Backtrace:
Application: System Settings (systemsettings5), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
