Bug ID: 416520
Summary: Plasma crash when dragging widget from desktop to
panel
Product: plasmashell
Version: 5.17.5
Platform: Archlinux Packages
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: putr...@gmail.com
CC: plasma-b...@kde.org
Target Milestone: 1.0
Application: plasmashell (5.17.5)
Qt Version: 5.14.0
Frameworks Version: 5.66.0
Operating System: Linux 5.4.13-arch1-1 x86_64
Distribution: "Arch Linux"
-- Information about the crash:
- What I was doing when the application crashed:
Drag a CPU load widget to a panel from the desktop quickly. Sometimes it
happens even when I try it slowly as well.
- Custom settings of the application:
There's only the default panel with the show desktop button removed at the
bottom, plus a new widened panel at the top (could be at the sides too, still
happens) and the CPU load widget.
The crash can be reproduced every time.
-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/usr/lib/libthread_db.so.1".
