Version: (using KDE 4.2.2) OS: Linux Installed from: Slackware Packages Please bear with me. I am no expert so I could get some things wrong. System is Slackware 12.2 with updates + KDE 4.2.2 installed from recompiled SlackBuild scripts. KDE 4.2.2 works great for me. Short story is, when I visit the website: http://forodelderecho.blogcindario.com the page loads for a while and then crashes every time. I suspect the crash is related to some stupid web advertisement code -- looks like the site is on one of those free hosting plans that forces you some pretty annoying ads. I don't know if the crash is related to KHTML, or JavaScript, or both. However, upon inspection of the source code of the crashing website it appears that the highest suspects are three pieces of JavaScript junk that are loaded from the URLS: http://contadores.miarroba.com/ver.php?id=513546 http://online.miarroba.com/ver.php?id=13634858 http://votaciones.miarroba.com/ver.php?id=46484&idc=1 Backtrace says it's of no use (I turned off debugging at compile time). However, I am going to crash Konqui again to paste it. In my system the crash is predictable and unavoidable, and the trigger is the load of the above mentioned website. How to reproduce: Just visit http://forodelderecho.blogcindario.com and see what happens ;-) I would appreciate if you could fix this. I'm sick of having to use Firefox when I have a much better browser in Konqui. Regards, Eduardo Sánchez Member, KDE-ES Spanish translation team http://es.l10n.kde.org

Created attachment 32790 [details] Reduced test case (very odd use of JavaScript IMHO) The test case is not completely self-contained - it loads an external JS file with the content: document.write("") parent.vt_ma_cambiadatos_s46484_c(1) Putting that into the test case file somehow didn't work for me. With 4.2.2 I get the same bt as Darío (segfault in khtml::HTMLTokenizer::notifyFinished ()). With recent trunk, all the frames up to that function appear in the bt as well, but it goes on and finally hits an assert (both with the original page and my test case): konqueror: /home/kde-devel/kde/src/KDE/kdelibs/khtml/html/htmltokenizer.cpp:185: void khtml::HTMLTokenizer::reset(): Assertion `m_executingScript == 0' failed.
(In reply to comment #3) > document.write("") > parent.vt_ma_cambiadatos_s46484_c(1) Correction: that's not really the contents of the external script. I got fooled by the '&'s in the URL and passed the wrong parameters to the PHP file when loading it in Konqueror ;-). It should be possible to improve the test case then...
Created attachment 32791 [details] JS which is part of an improved test case - contains only "parent.f1()"
Created attachment 32792 [details] Improved test case That's about as small as I can get it, I think :-)
Thanks for the testcase
Crash confirmed with the testcase on both KDE 4.4.5 and 4.5.0

Thank you for the crash reports. As it has been a while since this was reported, can you please test and confirm if this issue is still occurring or if this bug report can be marked as resolved. I have set the bug status to "needsinfo" pending your response, please change back to "reported" or "resolved/worksforme" when you respond, thank you.
Hi Justin, thanks for the comment. Reverting back to REPORTED. Using the latest testcase files, using Konqueror 20.12 Konqueror crashes in both KHTML and WebEngine rendering engines. I'm using the following configuration: Operating System: Slackware64-current (post 14.2 development) KDE Plasma Version: 5.20.4 KDE Frameworks Version: 5.77.0 Qt Version: 5.15.2 Kernel Version: 5.4.83 OS Type: 64-bit Processors: 8 × Intel® Core™ i7-8550U CPU @ 1.80GHz Memory: 15,5 GiB of RAM Graphics Processor: Mesa Intel® UHD Graphics 620 It was nice to go back to Konqi. Brought back fond memories. If we could only manage to give it a good adblocker and some fixes like these it could be again my daily driver. It's a fantastic piece of software
