Application: systemsettings5 (5.2.2)

Qt Version: 5.4.1
Operating System: Linux 3.19.0-30-generic x86_64
Distribution: Ubuntu 15.04

-- Information about the crash:
Fresh install of Kubuntu 15
When I'm trying to open settings for "Window style" (can't tell exact name of the item, because have localised version) - the config windows always force closed.

The crash can be reproduced every time.

-- Backtrace:
Application: Параметры системы (systemsettings5), signal: Aborted
