Bug 361527

Application: kinfocenter (5.5.4)

Qt Version: 5.5.1
Operating System: Linux 4.4.0-17-generic i686
Distribution: Ubuntu Xenial Xerus (development branch)

-- Information about the crash:
- What I was doing when the application crashed: I closed the window of Kinfocenter

- Unusual behavior I noticed: other applications in Kontact, have the same behavior : "configure Kontact, configure kaddress...

The crash can be reproduced every time.

-- Backtrace:
Application: Centre d'informations de KDE (kinfocenter), signal: Segmentation fault
