Application: kinfocenter (5.5.1)

Qt Version: 5.5.1
Operating System: Linux 4.3.3-gentoo x86_64
Distribution: "Gentoo Base System release 2.2"

-- Information about the crash:
- Opened Kinfocenter
- Navigated a few categories (minimum I've gotten a crash with is opening "Energy information" followed by "Graphical Information/Wayland" (which has no info on my install))
- Closed Kinfocenter

Opening other category combinations doesn't lead to a crash, but for "unfortunate" combinations I get crashes 100% of the time

The crash can be reproduced every time.

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