Description Max Behling 2018-01-06 04:07:24 UTC

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
