Bug 348372

Application: kinfocenter (5.3.0)

Qt Version: 5.4.1
Operating System: Linux 4.0.4-301.fc22.x86_64 x86_64
Distribution (Platform): Fedora RPMs

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

Launch kinfocenter and select 'Energy Information'. Wait until all 'Application Energy Consumption' data is shown. Then close kinfocenter. This causes kinfocenter to crash.

System: Fedora 22 x64

The crash can be reproduced every time.

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