Bug ID: 388605
Summary: System settings crash after typing into the search bar
Product: systemsettings
Version: 5.11.5
Platform: Archlinux Packages
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: max.behli...@gmail.com
Target Milestone: ---
Application: systemsettings5 (5.11.5)
Qt Version: 5.10.0
Frameworks Version: 5.41.0
Operating System: Linux 4.14.11-1-ARCH x86_64
Distribution (Platform): Archlinux Packages
-- Information about the crash:
- What I was doing when the application crashed:
I opened the system settings application and was looking for a settings menu
related to the panel at the bottom of the screen that contains the taskbar,
clock, system tray, etc. I typed the term "panel" into the search bar, and the
application crashed about 0.5 seconds after I typed the full term. I opened it
up to try again to investigate the bug, and it crashed again after typing into
the search bar. I tried other search terms as well, and it seems to crash about
0.5 seconds after I stop typing regardless of the search term. It does not
crash every time, but I would say about 60% of the time it crashes for me.
The crash can be reproduced sometimes.
-- Backtrace:
Application: System Settings (systemsettings5), signal: Segmentation fault
