Application: systemsettings5 (5.4.1)

Qt Version: 5.4.2
Operating System: Linux 4.2.0-25-generic x86_64
Distribution: Ubuntu 15.10

-- Information about the crash:
- What I was doing when the application crashed:
ouvrir configuration du systeme
clicker sur apparence des applications
clicker sur décoration des fenetres > plantage

plantage certainement du a une nouvelle deco , mais je ne sais pas la quelle.

The crash can be reproduced every time.

-- Backtrace:
Application: Configuration du système (systemsettings5), signal: Segmentation fault
