Note: This issue came up when kdiff3 using via 'git mergetool'. i.e after merge is done 'save' and 'quit' crashes kdiff3 - and git aborts Work-around [for git mergetool usage] is: - do merge in kdiff3 - [do not save] - quit - now a dialog box prompts to 'save and quit' - so click this dialog box. [no crash] I can't reproduce. kdiff3-1.8.1-3.fc31 has been pushed to the Fedora 31 testing repository. If problems still persist, please make note of it in this bug report.

You can provide feedback for this update here: https://bodhi.fedoraproject.org/updates/FEDORA-EPEL-2020-be568a097a I'm still seeing this issue with kdiff3-1.8.1-4.fc31 $ rpm -q kdiff3 kdiff3-1.8.1-4.fc31.x86_64 balay@sb /home/balay $ kdiff3 .bashrc .bashrc QSocketNotifier: Can only be used with threads started with QThread Segmentation fault (core dumped) balay@sb /home/balay $ This machine went through fedora version updates via dnf. Another machine [with a fresh f31 install] does not give this problem [even with kdiff3-1.8.1-2.fc31]. Also I don't get the 'QSocketNotifier: Can only be used with threads started with QThread' message on this box. So update to f31. And let's wait 1.8.2. It will be soon. Created attachment 1652823 [details] valgrind log > So update to f31. Not sure I understand. This breakage is on F31 I'm attaching valgrind log - hoping its useful. $ valgrind -q --tool=memcheck --num-callers=30 --track-origins=yes --log-file=kdiff3-val.log kdiff3 .bashrc .bash_profile And here are the packages referred in this log. glibc-2.30-8.fc31.x86_64 kdiff3-1.8.1-4.fc31.x86_64 qgnomeplatform-0.6.0-2.fc31.x86_64 qt5-qtbase-5.13.2-1.fc31.x86_64 qt5-qtbase-gui-5.13.2-1.fc31.x86_64 qt5-qtwayland-5.13.2-2.fc31.x86_64 Additional note: I just tried logging into gnome/xorg instead of default gnome/wayland - and there is no error. On switching back to gnome/wayland - I get this error. kdiff3-1.8.1-4.fc31 has been pushed to the Fedora 31 testing repository. If problems still persist, please make note of it in this bug report.

Please look at this ticket https://bugs.kde.org/show_bug.cgi?id=407745 And if it is not your problem - create new one.
