Application: konsole (19.08.0)

Qt Version: 5.12.5
Frameworks Version: 5.61.0
Operating System: Linux 5.3.6-300.fc31.x86_64 x86_64
Distribution (Platform): Fedora RPMs

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

I was using Plasma 5.16.5 on Wayland in Fedora 31. I had Konsole 19.8.0 running with two tabs open. I opened VLC 3.0.9 and selected open a file. An error message stated that the vlc file opening process had exited unexpectedly. Konsole showed an error message which disappeared before I could read all of it. Konsole disappeared. I started konsole again. I right-clicked in konsole and selected Open File manager. Konsole crashed. I'm unsure if the konsole trace is from the first or second crash. The trace showed the error message that the Wayland connection broke "The Wayland connection broke. Did the Wayland compositor die?". Plasma didn't crash when that happened.

- Unusual behavior I noticed:
Konsole showed (Not Responding) in the title bar, and the colours in konsole faded before it crashed.

-- Backtrace:
Application: Konsole (konsole), signal: Aborted
Using host libthread_db library "/lib64/libthread_db.so.1".
