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.
