SUMMARY *** NOTE: If you are reporting a crash, please try to attach a backtrace with debug symbols. See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports *** I have Ctrl+Shift+K set up to clear scrollback and reset. STEPS TO REPRODUCE 1. Open Konsole 2. Type <Ctrl>+<Shift>+k 3. Watch it crash OBSERVED RESULT Crash EXPECTED RESULT This used to work. SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: OpenSUSE 15.4 (available in About System) KDE Plasma Version: 5.27.3 KDE Frameworks Version: 5.104.0 Qt Version: 5.15.8 ADDITIONAL INFORMATION I did see some strange behavior. When I logged in after the last update some of my konsole settings seem to have changed. The menu bar disappeared and the tabs moved from the bottom to the top. I was able to fix this, however.

It looks like it's crashing here in session/SessionController.cpp: 994 void SessionController::updateCodecAction(QTextCodec *codec) 995 { 996 _codecAction->setCurrentCodec(QString::fromUtf8(codec->name())); 997 } 998 codec is NULL in gdb. Note that I am seeing a crash in the same place when I attempt to switch my profile, no matter what profile I select. I can, however, create a new tab and duplicate a tab. Changing the character encoding also causes a trap when I attempt to change from UTF-8 to default. Again, the crash is in the same place. I do not know enough about Konsole to know why the name appears to be NULL.
With some more digging it looks like it was due to the parent pointing to a non-existent profile in Shell.profile. I was getting the following message when starting Konsole: org.kde.konsole.profile: Could not load profile from "/home/aaronw/.kde4/share/apps/konsole/.profile" After manually removing the parent line in Shell.profile it seems to have stopped crashing. It still may be a bug, though, since it should not crash. Probably since I have a lot of cruft going back well over a decade floating around my home directory.

Git commit 9aef76a028eaf9c498761fc6ba487970e5a7af13 by Kurt Hindenburg, on behalf of Kurt Hindenburg. Committed on 02/05/2023 at 00:06. Pushed by hindenburg into branch 'master'. Do not allow an invalid parent to be set in profiles There are numerous crashes that come from this.
