Bug ID: 374153
Summary: systemsettings5 crash while configuring window
titlebar buttons
Product: systemsettings
Version: 5.8.2
Platform: openSUSE RPMs
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: someuniquen...@gmail.com
Target Milestone: ---
Application: systemsettings5 (5.8.2)
Qt Version: 5.6.1
Frameworks Version: 5.26.0
Operating System: Linux 4.6.2-4.g14295d6-default x86_64
Distribution: "openSUSE Leap 42.2"
-- Information about the crash:
- What I was doing when the application crashed:
Go to the "application style" -> "window decorations" -> "buttons"
Drag avaliable button handlers quickly to and from titlebar. Sometimes it
crashes.
The crash can be reproduced sometimes.
-- Backtrace:
Application: System Settings (systemsettings5), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
