Bug ID: 422197
Summary: Plasma crash after update, but only if background
picture is missing + no plasma response
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: flarel...@web.de
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 4.15.0-101-generic x86_64
Windowing system: X11
Distribution: KDE neon User Edition 5.18
-- Information about the crash:
- Unusual behavior I noticed:
I have every couple of starts a black plasma screen on one monitor (the second
is fine), but only in the position of the background picture. Task bar is
working fine. Plasma crashed then (~10 min later) when updateing the disti (KDE
Neon) with discover.
Before that the compositior didn't started and I kicked the opengl mode
manually.
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".
