Some questions as I cannot reproduce the crash. Does it happen only for this file or for other files, too? You are using quite recent Qt and KDE libraries. Did the crash happen a few days/weeks earlier befor you upgrade? Can you please launch KBibTeX on the command line and submit everything that is printed to stdout and stderr?
It seems to happen for all files I've tried. I haven't tried using kbibtex before so I can't tell if it broke only recently
Created attachment 136026 [details] console output
Hm, I still cannot reproduce the problem or deduce what the problem is. Can you please test the lastest version using the following approach: 1. Get the script 'run-kbibtex.sh' as described here: https://userbase.kde.org/KBibTeX/Development#Quick_Start_to_Run_KBibTeX_from_Git 2. Simply run bash run-kbibtex.sh This will download, compile, and run the lastest KBibTeX commit from Git, but everything will be done in /tmp, so it will neither touch your regular installation nor your current configuration. If no crash occurs here, the problem you observed is most likely with your regular installation. Otherwise, I'll have to dig deeper ...

This is caused by Qt commit https://code.qt.io/cgit/qt/qtbase.git/commit/?h=5.15&id=4796296ed6d7b05e2ba94e5a8a28c48350a3c492

Is there a problem on KBibTeX which someone (I?) need to fix or is it an issue in Qt which I can do little about until it is resolved somehow in Qt upstream?
It is already fixed in Qt (+KDE patches)
Created attachment 148913 [details] New crash information added by DrKonqi kbibtex (0.9.90) using Qt 5.15.3 - What I was doing when the application crashed: opening a '.bib' - file from the dolphin context menu or opening a '.bib' - file from the downloads-list in firefox and then choosing KBibTeX to handle the file. opening a '.bib' - file from inside KBibTex. Happens with different '.bib'-files. -- Backtrace (Reduced): #4 0x00007fc12a182d40 in FileModel::element (this=0x0, row=0) at ./src/data/models/filemodel.cpp:388 #5 0x00007fc12a4ae6e4 in SortFilterFileModel::filterAcceptsRow (this=0x55fd81ef2d50, source_row=<optimized out>, source_parent=...) at ./src/gui/file/sortfilterfilemodel.cpp:147 #6 0x00007fc1287dfc1e in QSortFilterProxyModelPrivate::create_mapping (this=this@entry=0x55fd81ef3e20, source_parent=...) at itemmodels/qsortfilterproxymodel.cpp:504 #7 0x00007fc1287e986d in QSortFilterProxyModel::setSourceModel (this=0x55fd81ef2d50, sourceModel=<optimized out>) at itemmodels/qsortfilterproxymodel.cpp:2149 #8 0x00007fc12a4afac5 in SortFilterFileModel::setSourceModel (this=this@entry=0x55fd81ef2d50, model=0x55fd81ef3c20) at ./src/gui/file/sortfilterfilemodel.cpp:39
I have the same issue. I installed KBibTeX on my new computer May 18 and at my first attempt to open a ".bib" file, the program crashed. I made several attempts with different ".bib" files and every time, there was a crash. I can create a new file and save it, but when I try to reopen it, the app crashes. info KBibTeX version 0.9.90 (Kubuntu package) Operating System: Kubuntu 22.04 KDE Plasma Version: 5.24.4 KDE Frameworks Version: 5.92.0 Qt Version: 5.15.3 Kernel Version: 5.15.0-30-generic (64-bit) Graphics Platform: X11 Processors: 4 × AMD Ryzen 3 2200G with Radeon Vega Graphics Memory: 13.6 Gio of RAM Graphics Processor: AMD Radeon Vega 8 Graphics
I made further tests and I found this: if I create a ".bib" file without any entry in it and save it, I can reopen it without problem. But if I add some information in the file, save, close and try to reopen it, then KBibTeX crashes. Also, I upgraded my old laptop to Kubuntu 22.04 LTS this week and KBibTeX, which was working fine before with Kubuntu 21.10, now crashes the same way when I try to open a non-empty ".bib" file. I suspect there is a link between this bug and bug 453455.
This is a Qt bug that was fixed a year ago in the KDE patch collection. You should ask your distro to switch their Qt packages to the patch collection or at least backport the fix for this.
(In reply to Antonio Rojas from comment #15) If the bug was fixed last year, how come I never had problem with KBibTeX until I upgraded to Kubuntu 22.04 last month?
(In reply to Antoine D. from comment #16) > (In reply to Antonio Rojas from comment #15) > If the bug was fixed last year, how come I never had problem with KBibTeX > until I upgraded to Kubuntu 22.04 last month? For the same reason you're having the bug *now*: because your distro is shipping an old version of Qt. This bug was introduced upstream in Qt 5.15.3.
(In reply to Antonio Rojas from comment #17) Thank you for your help and explanations. I now use the Flatpak version of KBibTeX. It is not perfect but at least I can open a file and do something in KBibTeX. Asking and waiting for Ubuntu to add the patch collection doesn't seem to be an option: https://www.kubuntuforums.net/forum/newbie-support/help-the-new-guy/663425-how-can-i-get-the-qt5-patch-collection-to-solve-my-crashing-kbibtex-problem

It is a little bit unclear, but does this problem still exist? Have you tested the latest code either from branch 'master' or 'kbibtex/0.10'?
I can verify that kbibtex 0.10.0-1build1 (from Ubuntu noble) no longer crashes on my usecase. Closing issue.
