Bug ID: 470191
Summary: Crash in Configure Desktop and Wallpaper when Latte
Dock is installed
Classification: Plasma
Product: plasmashell
Version: 5.27.5
Platform: Archlinux
OS: Linux
Status: REPORTED
Severity: crash
Priority: NOR
Component: generic-crash
Assignee: plasma-b...@kde.org
Reporter: tildear...@protonmail.com
Target Milestone: 1.0
SUMMARY
plasmashell will crash if plasma_containmentactions_lattecontextmenu.so loads
by going to Configure Desktop and Wallpaper... > Mouse Actions.
I don't know whether to report it as a plasmashell bug or a latte-dock one, so
I reported it as plasmashell.
May not reproduce all the time.
