Bug ID: 386997
Summary: System settings window crashed by searching
Product: systemsettings
Version: 5.11.3
Platform: Ubuntu Packages
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: isa-...@gmx.de
Target Milestone: ---
Application: systemsettings5 (5.11.3)
Qt Version: 5.9.1
Frameworks Version: 5.39.0
Operating System: Linux 4.13.0-16-generic x86_64
Distribution: Ubuntu 17.10
-- Information about the crash:
- What I was doing when the application crashed:
Opened the system settings and typed "wallpaper" in the search field very
quickly; however while typing (and simultaneously searching) the system
settings crashed. Could reproduce it four times; however it does not always
happen. Maby it's a race condition.
The crash can be reproduced every time.
-- Backtrace:
Application: Systemeinstellungen (systemsettings5), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
