Bug ID: 405023
Summary: systemsettings crashes when double clicking an item in
icon view
Product: systemsettings
Version: 5.15.2
Platform: Compiled Sources
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: j...@ristioja.ee
Target Milestone: ---
Application: systemsettings5 (5.15.2)
(Compiled from sources)
Qt Version: 5.12.1
Frameworks Version: 5.55.0
Operating System: Linux 4.20.13-gentoo x86_64
Distribution: "Gentoo Base System release 2.6"
-- Information about the crash:
- What I was doing when the application crashed:
I think I upgraded qt/kde/plasma before a reboot.
1) Started "systemsettings5"
2) Double clicked on "Workspace theme" or "Desktop Behavior"
- Unusual behavior I noticed:
Desktop wallpaper was missing on login, and when I right-clicked the desktop
and chose "Configure Desktop", a window titled "Desktop Settings - Plasma" with
literally no contents appears, only a border/frame. So that when something
behind that window redraws itself, e.g. when I'm typing this text, it also
appears within the border, i.e. the window is completely transparent.
The crash can be reproduced every time.
-- Backtrace:
Application: System Settings (systemsettings5), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
