kbibtex crashes on startup when using git revision 600c246 with no further error messages. It used to work fine a few days ago. Reproducible: Always
(In reply to Gandalf Lechner from comment #0) > kbibtex crashes on startup when using git revision 600c246 with no further > error messages. It used to work fine a few days ago. I cannot reproduce this problem with exactly this commit. Does KBibTeX automatically open some files you had opened in the previous session? Do you see any output on the console when starting KBIbTeX on the command line? The master branch of KBibTeX for KDE4 was recently branched into 'kbibtex/0.7', whereas the Frameworks 5 version became 'master'. Can you reproduce the problem with either of the branches?
After another checkout I needed to install a couple of new packages, probably due to the kf5 version. Now I get a message "no part available for file .." when trying to open a .bib file. No crash, but the file is not opened.
Compilation and installation differs slightly between the KDE4 version and the KF5 version. Please see if the instructions provided at https://userbase.kde.org/KBibTeX/Development help you on how to install KBibTeX.

I just tried with a new checkout - compilation and installation works fine as far as I can tell, but kbibtex crashes right after starting it, with the message pasted below. Is there a simple way of checking that my installation is correct? ######### kbibtex.program: Starting KBibTeX version Git revision c451d02 (master) QCommandLineParser: option not defined: "author" QCommandLineParser: option not defined: "license" QCommandLineParser: option not defined: "desktopfile" kbibtex.data: Creating File instance 100000 kbibtex.program: No Okular part for PDF or PostScript document preview available. kbibtex.program: HTML KPart is available, using it instead of WebEngine or WebKit (neither available) for HTML/Web preview. kbibtex.program: Located KPart service: "kbibtexpart" with description "KParts-Komponente zum Betrachten und Editieren von Bibliographiedateien" kbibtex.program: Using service "BibTeX-Betrachter und -Editor" ( "KParts-Komponente zum Betrachten und Editieren von Bibliographiedateien" ) for mime type "text/x-bibtex" Speicherzugriffsfehler (Speicherabzug geschrieben)
> Is there a simple way of checking that my installation is correct? > Speicherzugriffsfehler (Speicherabzug geschrieben) The error message points to a real crash, for which I would consider an incomplete as less likely. There is a TechBase article on how to generate useful crash reports: https://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports You may need to configure&compile KBibTeX with debugging enabled (-DCMAKE_BUILD_TYPE=debug) and have KDE's kcrash installed. Hopefully this will provide you with more information why the crash happens.
Today I tried again, with a fresh checkout. I also made sure that I compiled the debug version, and have all packages with "kcrash" in their names installed. The result is still an immediate crash after starting the program (can see the program window only for a split second), and the message kbibtex.program: Starting KBibTeX version Git revision 82140e1 (master) QCommandLineParser: option not defined: "author" QCommandLineParser: option not defined: "license" QCommandLineParser: option not defined: "desktopfile" kbibtex.data: Creating File instance 100000 kbibtex.program: No Okular part for PDF or PostScript document preview available. kbibtex.program: HTML KPart is available, using it instead of WebEngine or WebKit (neither available) for HTML/Web preview. kbibtex.program: Located KPart service: "kbibtexpart" with description "KParts-Komponente zum Betrachten und Editieren von Bibliographiedateien" kbibtex.program: Using service "BibTeX-Betrachter und -Editor" ( "KParts-Komponente zum Betrachten und Editieren von Bibliographiedateien" ) for mime type "text/x-bibtex" Speicherzugriffsfehler (Speicherabzug geschrieben) I have in the meantime switched from kubuntu 15.10 to kubuntu 16.04, but the situation looks the same as before. Any idea what I could do to fix this?
Maybe this can help you to collect data on the crash: https://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports
Since I really miss kbibtex, I now started experimenting with gdb (which I have no experience with) to produce more information on this crash. As before, kbibtex starts fine, but crashes once I click "new" or "open". In gdb, it says Thread 1 "kbibtex" received signal SIGSEGV, Segmentation fault. 0x00007ffff7b4a036 in FilterBar::comboboxStatusChanged (this=0x14cac80) at /home/gandalf/down/git/kbibtex/src/gui/widgets/filterbar.cpp:275 275 d->buttonSearchPDFfiles->setEnabled(d->comboBoxField->currentIndex() == 0); The kbibtex window does however not close, it stays there but is completely unresponsive. Then I read somewhere that I should type "thread apply all backtrace" into gdb, which produces further output that I paste below. Is this useful information or should I try something else?

The problem may have been caused by the premature establishment of signal-slot connections in the FilterBar class. I rearranged this code section in the lastest commit: http://commits.kde.org/kbibtex/75b13672d7f3e300 Please test if the crash has been fixed.
Thanks a lot, this indeed fixed the crash! :-) Now kbibtex starts fine; the only problem is that it seems not to be able to load pdf previews (which worked fine in the 0.6 version). It says "Don't know how to show mimetype application/pdf" ... but that is probably an unrelated issue.

KF5 programs need a KF5-based Okular to show PDF files. Such a version of Okular has not yet been officially released. Some distributions offer experimental packages to install the latest version from Git.
At the moment, I do not experience any crashes, so this one seems to be fixed as well
