Bug ID: 426126
Summary: plasmashell crashed from mouseover taskbar
Product: plasmashell
Version: 5.14.5
Platform: Debian stable
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: l...@lx21.de
CC: plasma-b...@kde.org
Target Milestone: 1.0
Application: plasmashell (5.14.5)
Qt Version: 5.11.3
Frameworks Version: 5.54.0
Operating System: Linux 4.19.0-10-amd64 x86_64
Distribution: Debian GNU/Linux 10 (buster)
-- Information about the crash:
- What I was doing when the application crashed:
--I moved the mouse over the taskbar, which is normally hided in my settings,
and after showing the taskbar, the system freezes for about 30-40 seconds.
--Normally (by moving the mouse to the taskbar) I wanted to switch from dolphin
to konsole when the crash happens.
--There were no big operations running in dolphin or konsole but a backup
script (cp -ru ... ...) was running as cronjob in the background.
--By the way: the memory used by plasmashell is increasing from 90MB (after
login) up to 300-400MB in 20-30 minutes. And there isn't really a difference
between working with the system or not working with it...
The crash can be reproduced sometimes.
-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
