Bug ID: 409465
Summary: Desktop Crash
Product: plasmashell
Version: 5.16.2
Platform: Archlinux Packages
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: skirmish...@gmail.com
CC: plasma-b...@kde.org
Target Milestone: 1.0
Application: plasmashell (5.16.2)
Qt Version: 5.13.0
Frameworks Version: 5.59.0
Operating System: Linux 5.1.15-arch1-1-ARCH x86_64
Distribution: "Arch Linux"
-- Information about the crash:
- What I was doing when the application crashed:
I had just unlocked the screen after being away from the machine for a time.
The screen had auto-locked in my absence.
- Unusual behavior I noticed:
Background went black, then the taskbar disappeared. I think only one
application that I had opened previously was visible at this point. After this,
the desktop reloaded and I was presented with a crash report.
-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/usr/lib/libthread_db.so.1".
