Bug ID: 425952
Summary: Intermittent plasmashell crashes when interacting with
panel
Product: plasmashell
Version: 5.18.5
Platform: Gentoo Packages
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: x0r+...@x0r.fr
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 5.4.38-gentoo-x86_64 x86_64
Windowing system: X11
Distribution: Gentoo/Linux
-- Information about the crash:
- What I was doing when the application crashed:
It doesn’t always happen, but I’ve always had it happen when interacting with
my main panel in some way. I know for sure it happened to me in the following
circumstances:
(a) clicking on a button to change a task;
(b) clicking on an item in the notification area;
(c) plugging in a new volume (USB, audio CD…);
(d) more rarely, completely at random.
I’ve marked a possible duplicate since the backtrace looks similar.
The crash can be reproduced sometimes.
-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
