Bug ID: 413219
Summary: systematic crash plasma after update to 5.17
Product: plasmashell
Version: 5.17.0
Platform: unspecified
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: mixa5...@gmail.com
CC: plasma-b...@kde.org
Target Milestone: 1.0
Application: plasmashell (5.17.0)
Qt Version: 5.13.1
Frameworks Version: 5.63.0
Operating System: Linux 5.0.0-31-generic x86_64
Distribution: KDE neon User Edition 5.17
-- Information about the crash:
- Unusual behavior I noticed:
Plasma falls at arbitrary points in time, regardless of the tasks I have
launched. I noticed this behavior of the working environment after upgrading to
version 5.17. On another computer of a similar configuration, but plasma 5.16.5
does not crash.
The crash can be reproduced every time.
-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
