Bug ID: 421835
Summary: Plasma desktop crashes when I'm trying to move an icon
Product: plasmashell
Version: 5.18.5
Platform: unspecified
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: vladma...@gmail.com
CC: plasma-b...@kde.org
Target Milestone: 1.0
Application: plasmashell (5.18.5)
Qt Version: 5.14.2
Frameworks Version: 5.70.0
Operating System: Linux 5.3.0-53-generic x86_64
Windowing system: X11
Distribution: KDE neon User Edition 5.18
-- Information about the crash:
I dragged the Qt Creator Icon from application launcher and clicked "copy here"
in the context menu that appeared. Then I tried to change position of the icon
on the desktop, but it crashed instead. After a few seconds it relaunched and
the icon was on its original place. When I repeated the actions crash happened
again but plasma wouldn't relaunch itself so I had to reboot. The problem
happened again after reboot. I'm using KDE Neon user edition from the offcical
website with all the updates (available in discover) installed. I didn't really
change anything except for global theme (breeeze dark) and enabling wobbly
windows. The bug doesn't occur when I try to move icons related to files and
links but only when I move application icons (Chromium browser and some steam
also made this bug happen).
The crash can be reproduced every time.
-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
