Bug ID: 402975
Summary: Crash after Plasma just launches.
Product: plasmashell
Version: 5.14.4
Platform: Archlinux Packages
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: broekhoff.joc...@gmail.com
CC: plasma-b...@kde.org
Target Milestone: 1.0
Application: plasmashell (5.14.4)
Qt Version: 5.12.0
Frameworks Version: 5.53.0
Operating System: Linux 4.20.0-arch1-1-ARCH x86_64
Distribution (Platform): Archlinux Packages
-- Information about the crash:
- What I was doing when the application crashed:
Just booting my computer. This crash doesn't happen often, just one in a while.
I can see the toolbar appearing for a split second, then everything disappears,
the screen goes black and the mouse pointer looks like it's in an old or
default style.
I'm always able to re-launch Plasma by hitting Alt+Spacebar (which does still
work) and entering "kstart5 plasmashell".
The crash can be reproduced sometimes.
-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/usr/lib/libthread_db.so.1".
