Operating System: Linux 4.0.5-gentoo x86_64
Distribution: "Gentoo Base System release 2.2"

-- Information about the crash:

opening several settings like window manager settings, appearance settings, and navigating back
crashed when navigating back or opening something (don't remember exactly)

The crash can be reproduced sometimes.

-- Backtrace:
Application: Параметры системы (systemsettings5), signal: Segmentation fault
