Description skirmish666 2019-07-03 15:23:38 UTC

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".

The crash does not appear to be in any KDE code. Does this still happen to you in either Plasma 5.18 (the current LTS version) or Plasma 5.21 (the latest released version)? Preferably when using the latest Qt version (5.15.2 or newer)?
