It would be useful to have a stack backtrace of the qwebengine_convert_dict crash. It should be possible to produce one from the core dump. Thanks for replying quickly, Kevin. The reason I reproduced this error using 'dnf reinstall' was because abrt refused to report the origin error, which I had noticed during a regular 'dnf update'. It claimed that there was not enough content to make it worth reporting, or words to that effect. If you can tell me how to get some better information, let me know, and I will try. We still do not have enough information to know what is going wrong. Any of those who are hitting the crash: Which hunspell-* packages do you have installed (i.e., what is the output of: rpm -qa 'hunspell-*')? (Maybe we can reproduce the crash if we install the same hunspell dictionary/ies?) # rpm -qa | grep hunspel hunspell-en-GB-0.20140811.1-17.fc33.noarch hunspell-en-0.20140811.1-17.fc33.noarch hunspell-en-US-0.20140811.1-17.fc33.noarch hunspell-1.7.0-7.fc33.x86_64 hunspell-uk-1.8.0-6.fc33.noarch hunspell-el-0.9-6.fc33.noarch hunspell-he-1.4-11.fc33.x86_64 And I still get the core dump if I reinstall qt5-qtwebengine-5.15.2-8.fc33.x86_64.rpm. Thanks for looking into this. :D I can reproduce this by installing hunspell-uk, which triggers the file scriptlet in qt5-qtwebengine: Ausgeführtes Scriptlet: hunspell-uk-1.8.0-5.fc32.noarch 1/1 /var/tmp/rpm-tmp.YZaQXp: Zeile 2: 55166 Trace/Breakpoint ausgelöst /usr/lib64/qt5/bin/qwebengine_convert_dict "$filename" "$bdicname" &> /dev/null The other hunspell-* packages you have installed do not trigger the crash. Neither does hunspell-ru. Now that I know how to reproduce the crash, I will obtain a backtrace from there. I have run: qwebengine_convert_dict /usr/share/myspell/uk_UA.dic /usr/share/qt5/qtwebengine_dictionaries/uk_UA.bdic manually and I get: [0210/005207.234422:FATAL:aff_reader.cc(123)] We don't support the IGNORE command yet. This would change how we would insert things in our lookup table. I suppose a quick hack would be to just change this line: https://code.qt.io/cgit/qt/qtwebengine-chromium.git/tree/chromium/chrome/tools/convert_dict/aff_reader.cc?h=83-based#n123 to a warning and, well, ignore ;-) the IGNORE command. So my proposal is to change line 123 (and probably also line 126) from LOG(FATAL) to LOG(WARNING) and see what happens. *** Bug 1947055 has been marked as a duplicate of this bug. *** Looks like this also crashes on hunspell-ar, see the duplicate (pointing to the same aff_reader.cc:123 line). *** Bug 1960489 has been marked as a duplicate of this bug. *** *** Bug 1979660 has been marked as a duplicate of this bug. *** *** Bug 1990972 has been marked as a duplicate of this bug. *** And now also on hunspell-fa (fa_IR). FEDORA-2021-043fa12473 has been submitted as an update to Fedora 34. https://bodhi.fedoraproject.org/updates/FEDORA-2021-043fa12473 That update does NOT fix this bug. The code that triggers the fatal error has not changed at all: https://code.qt.io/cgit/qt/qtwebengine-chromium.git/log/chromium/chrome/tools/convert_dict/aff_reader.cc?h=87-based This will likely never be fixed upstream and has to be fixed downstream (e.g., as per my comment #7).

FC34 crash
I reinstalled the package and it took a long time to finally crash. The file has the hunspell packages installed.
