Bug ID: 390857
Summary: KCM crashes when trying to load "window decorations"
Product: systemsettings
Version: 5.12.2
Platform: Archlinux Packages
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: normal
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: renyune...@gmail.com
Target Milestone: ---
Application: systemsettings5 (5.12.2)
Qt Version: 5.10.1
Frameworks Version: 5.43.0
Operating System: Linux 4.15.3-2-ARCH x86_64
Distribution (Platform): Archlinux Packages
-- Information about the crash:
- What I was doing when the application crashed:
I was opening the "window decoration" section, and KCM suddenly crashes. I
observed the "boarder size" is already displayed, but the center parts (themes)
are not.
(Not sure if relevant:)
I changed GTK fonts first, and then switched to "widget style" ("Fine Tuning"
section). Then I switched to "Window Decorations" and the crash happens
immediately.
The crash does not seem to be reproducible.
-- Backtrace:
Application: 系统设置 (systemsettings5), signal: Segmentation fault
Using host libthread_db library "/usr/lib/libthread_db.so.1".
