Application: kinfocenter (5.5.5)

Qt Version: 5.5.1
Operating System: Linux 4.4.0-22-generic x86_64

-- Information about the crash:
- What I was doing when the application crashed:
I closed the application after checking the information on OpenGL and when the window closed DrKonqi appeared saying that KInfoCenter crashed.

-- Backtrace:
Application: KDE Info Center (kinfocenter), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
