I booted the Fedora Rawhide/40 KDE Plasma live image Fedora-KDE-Live-x86_64-Rawhide-20231204.n.0.iso on bare metal. I started Konsole in Plasma 5.90.0 on Wayland. I ran WAYLAND_DEBUG=1 plasmashell --replace. To troubleshoot the plasmashell crashes at https://bugs.kde.org/show_bug.cgi?id=478086 I started Dolphin I quickly moved the cursor over the Konsole icon in the task manager to the icons to its left (Firefox, Dolphin, Discover, System Settings). plasmashell crashed when I did that and the panel disappeared and reappeared automatically a few seconds later. drkonqi appeared. I selected Developer information, and created a trace. I tried to report through bugs.kde.org through drkonqi, but drkonqi crashed at the point that a list of possible duplicate reports was shown and I clicked on one of the reports. The crashing thread 7 had a segmentation fault with a trace like that in this report.

Git commit a0bd2fa0cfbde80032cf45e657ad21da4df74a41 by Harald Sitter. Committed on 07/12/2023 at 18:02. Pushed by sitter into branch 'master'. duplicates detection: drop support with the advance of automatic crash reporting the duplicates detection isn't really necessary anymore. it also hasn't been all that great. the UI was terrible, the UX was terrible, the code was expansive, parsing random comments from bugzilla had potential of crashing drkonqi ...
