Bug ID: 456990
Summary: Plasma (plasmashell), signal: Segmentation fault -
s_kcrashErrorMessage: std::unique_ptr<char []> =
{get() = 0x0}
Product: plasmashell
Version: 5.24.4
Platform: openSUSE RPMs
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: bugrprt21...@online.de
CC: k...@davidedmundson.co.uk
Target Milestone: 1.0
Application: plasmashell (5.24.4)
Qt Version: 5.15.2
Frameworks Version: 5.90.0
Operating System: Linux 5.14.21-150400.22-default x86_64
Windowing System: Wayland
Distribution: "openSUSE Leap 15.4"
DrKonqi: 5.24.4 [KCrashBackend]
-- Information about the crash:
- What I was doing when the application crashed:
Logging in to a Wayland session - black screen - Monitor displayed "No signal"
and dropped into standby mode. Moving the mouse had no effect.
Powered the screen off and then on - the Plasma Session then appeared.
The crash can be reproduced sometimes.
-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
