Based on the backtrace, I suppose this probably doesn't happen on Wayland, right? (In reply to Nate Graham from comment #1) > Based on the backtrace, I suppose this probably doesn't happen on Wayland, > right? Actually this is really strange, because I always use wayland… is it possible that DrKonqi has a bug detecting Wayland? Maybe your system is set up strangely then? Your `kinfo` output in the first message said "Windowing System: X11". And it's crashing in X11-specific code. Can you verify? Well, maybe that time I used a X11 session for testing something, then I forgot… Today is what kinfo returns: $ kinfo Operating System: Gentoo Linux 2.17 KDE Plasma Version: 6.2.4 KDE Frameworks Version: 6.8.0 Qt Version: 6.8.1 Kernel Version: 6.12.4-gentoo-x86_64 (64-bit) Graphics Platform: Wayland Processors: 8 × Intel® Core™ i7-9700K CPU @ 3.60GHz Memory: 31.3 Gio of RAM Graphics Processor: AMD Radeon RX 7800 XT I will also check if kaccess crash on Wayland. Keep you informed. It happened again, and I swear I was using Wayland for my plasmashell session. Another crash also happened in the same conditions, I was using Wayland, but DrKonqi thinks I use X11: https://bugs.kde.org/show_bug.cgi?id=497444 *** This bug has been marked as a duplicate of bug 496218 *** |
