Description Matt Fagnani 2019-10-16 20:20:22 UTC 
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".

New crash information added by DrKonqi

konsole (19.12.1) using Qt 5.13.2

- What I was doing when the application crashed:

I was running Plasma 5.17.5 on Wayland in Fedora Rawhide with Qt 5.13.2, KF 5.66.0, Mesa 19.3.2. I opened Konsole 19.2.1. I opened a second tab. I ran coredumpctl gdb on a kwin_wayland crash which happened when logging out on the previous boot. I reported those type of kwin_wayland crashes at https://bugs.kde.org/show_bug.cgi?id=416147. The core dump file was 2.1 GB, and it took a few minutes for coredumpctl gdb to decompress and process the core dump. I ran bt in gdb to get a trace. Konsole stopped responding for about a minute with Not Responding in the title bar. Konsole's colours faded. Konsole disappeared. The trace in Dr. Konqi showed the error "The Wayland connection broke. Did the Wayland compositor die?" in frame 9 of the crashing thread 1. I've previously seen Konsole abort with that error as in my previous report here. I've also seen that error for 
plasmashell https://bugs.kde.org/show_bug.cgi?id=414116
ksysguard https://bugs.kde.org/show_bug.cgi?id=413901
system settings https://bugs.kde.org/show_bug.cgi?id=414118

The underlying problem might be in Qt particularly qtwayland.

Qt cannot recover from this error.
