Application: kinfocenter (5.3.0)

Qt Version: 5.4.1
Operating System: Linux 4.0.4-303.fc22.x86_64 x86_64
Distribution: "Fedora release 22 (Twenty Two)"

-- Information about the crash:
- What I was doing when the application crashed:
1) After I take a look on any details on "Energy Information" tab and I close the KInfoCenter.

2) The crash always happens if I click on "Energy Information" regardless of sequence.

3) The issue does not affect at all if I never click on "Energy Information" at all before I close the KInfoCenter.

The crash can be reproduced every time.

-- Backtrace:
Application: KDE Info Center (kinfocenter), signal: Aborted
