Bug 354973

Application: systemsettings5 (5.4.1)

Qt Version: 5.5.0
Operating System: Linux 4.2.5-300.fc23.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
I had opened System Settings and then closed it (without selecting any entires, as far as I remember).
Then after a few seconds, I tried to open it again and it crashed.

This might be a duplicate, but DrKonqi doesn't really allow me to specify so.

The crash does not seem to be reproducible.

-- Backtrace:
Application: System Settings (systemsettings5), signal: Segmentation fault
