Description kaspercool108 2019-03-23 12:09:00 UTC

Application: plasmashell (5.15.3)

Qt Version: 5.12.2
Frameworks Version: 5.56.0
Operating System: Linux 4.19.30-1-lts x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed: I was editing my task manager settings and the session just crashed. As far as I could find, editing the settings of any widgets crashes plasma for me.
This bug only occurs on my desktop PC running Arch Linux.
My laptop running the same distro does not have this problem.

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/usr/lib/libthread_db.so.1".
