Bug 381457

Application: kinfocenter (5.10.90)

Qt Version: 5.9.0
Frameworks Version: 5.36.0
Operating System: Linux 4.11.5-1-default x86_64
Distribution: "openSUSE Tumbleweed"

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

I was checking "wayland compositor information", closed it afterwards.

Steps to reproduce:
Open KinforCenter and go to "Graphical Information"
Under "wayland" fold "interfaces" (will trigger with outputs and seats as well)
Close it

The crash can be reproduced every time.

-- Backtrace:
Application: Info Center (kinfocenter), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
