Application: konsole (19.04.2)

Qt Version: 5.12.3
Frameworks Version: 5.59.0
Operating System: Linux 4.18.0-22-generic x86_64
Distribution: KDE neon User Edition 5.16

-- Information about the crash:
- What I was doing when the application crashed:

I was running tmux in a Konsole window with only one tab. I switched to another
Plasma activity and stopped the activity running the Konsole window, which lead 
to this crash.

-- Backtrace:
Application: Konsole (konsole), signal: Segmentation fault
