New crash information added by DrKonqi

konqueror (5.0.97) using Qt 5.7.1

- What I was doing when the application crashed:
I started konqueror from the command line like this:

> konqueror 'https://kde.org/'

- Unusual behavior I noticed:

konqueror asked which program I want to use to open the page (Type: HTML document).
I clicked on cancel and it crashed.

konqueror (5.0.97) using Qt 5.9.5

- What I was doing when the application crashed:

1) in the konsole, type "konqueror http://filmingcops.com/san-francisco-police-targeted-only-black-residents-in-drug-arrests-lawsuit-claims/"

2) click "no" when it asks you if you want to open with firefox

RESULT: crash

EXPECTED RESULT: open the URI

- Unusual behavior I noticed:

i've taken to starting konqueror from the konsole because if i click on the icon, it crashes without even making a window.

Thank you for reporting this crash in KDE software. As it has been a while since this issue was reported, can we please ask you to see if you can reproduce the crash with a recent software version?

If you can reproduce the issue, please change the status to "CONFIRMED" when replying. Thank you!
Comment 13 przxqgl 2022-10-10 15:00:14 UTC
i tried starting it from the console with the URI in the initial reporting of the bug, and it comes up without a problem.

however, if i try to browse somewhere else, it crashes, if i call it from the console WITHOUT a URI, it crashes, and if i try to start it from the GUI, it crashes.
Comment 14 Stefano Crocco 2022-10-13 12:41:50 UTC
Just to be sure I understood correctly:
- you ran `konqueror www.postillion.com` from the shell and it worked correctly. Then you tried navigating somewhere else from that page and it crashed
- running `konqueror` from the shell causes a crash
- running Konqueror frome somewhere in the GUI (for example, from the application launcher menu or entering `Konqueror` in KRunner) causes a crash

I tried navigating to www.postillion.com, but the host can't be reached. I don't get crashes running konqueror either from the shell or from the GUI. Could you please tell which distribution and  version of Konqueror and of the KDE frameworks you're using and, if possible, post a backtrace of the crashes?

Thanks

that is correct, however, i ran 'konqueror http://filmingcops.com/san-francisco-police-targeted-only-black-residents-in-drug-arrests-lawsuit-claims/' from the console.

i can start from the GUI with no URL about half the time. the rest of the time, konqueror never opens a window, and 'ps' gives me an ID that has failed.

kubuntu 20.04
KDE frameworks version 5.68.0
Qt version 5.12.8
konqueror version 5.0.97
Comment 16 Stefano Crocco 2022-10-13 18:21:42 UTC
It's an old version of Konqueror, and many things have changed in the new releases. Could you please verify which is your default web browser engine? (You can find in the General tab of Konqueror settings dialog, right below the "Home page settings": it can be WebEngine, WebKit or KHTML). Could you please also try creating a new user and seeing whether you have the same problems?

it's an old story which keeps coming back to haunt me...

well, my version of konqueror has a "settings" menu, but i don't know how to get to a "General tab of Konqueror settings dialog", so you'll have to do a better job of telling me what you want.

i could probably do that, with step-by-step instructions, but it is beyond my current capabilities as a user.

From the "Settings" menu, choose the "Configure Konqueror" entry to display the settings dialog. On the left, there's a tree (I'm working from memory, as this dialog has changed much in more recent versions of Konqueror). In these trees there's at least one, but most likely two "General" entries: you need the first (which should be, if I remember correctly, under the "Web behavior" entry). Clicking on it will display in the right side of the dialog a page with several configuration options: the third is labeled "Default web browser engine" (or something very similar). You should check what is selected for that option. Another way to do the same is opening any web page, then going to the "View" menu, choosing the "View mode" submenu and looking at the checked entry.

Another thing you can check (which I forgot in my last answer) are the settings in the "KDE Performance" page of the settings dialog. You can access it as described above: the page is one of the first in the tree on the left (I think the second one). Ensure that both entries in the page ("Preload an instance after desktop startup" and "Always try to have one preloaded instance") are unchecked. These options were quite broken in old versions of Konqueror and could lead to strange behaviors.

In that case, it's better not to try. It's not that difficult, but since it requires superuser access, a mistake could damage your system. A simpler, but less complete test, is to ensure that Konqueror isn't running (to do so, from a terminal run `killall konqueror`), then rename he file ~/.config/konquerorrc and the directory ~/.local/share/konqueror to something else (for example, ~/.config/konquerorrc_old and ~/.local/share/konqueror_old): this will reset your Konqueror configuration to the default values. You can then try running Konqueror again and see whether you have the same problems or not. If things not work correctly, there was something broken in your configuration files.

on my version of konqueror (version 5.0.97), when i select "Configure Konqueror" from the "Settings" menu, i do not get a tree on the left. i get selections for "Performance" and "Bookmarks" on the left: the choices for "Performance" are "Preload an instance after desktop startup" and "Always try to have one preloaded instance". the selections for "Bookmarks" are "Number of columns to show", "Show folder backgrounds", "Show bookmarks without folder", "Flatten bookmarks tree", "Show system places" and settings for a "Pixmap Cache"...

i am not sure what to do next.

when i select "Configure Konqueror" from the "Settings" menu, in the "Performance" section, "Always try to have one preloaded instance" was checked. i unchecked it. "Preload an instance after desktop startup" was not checked, and i left it that way.

using this method, the problems are the same as originally reported.

If I understand correctly what you're saying, I think either your Konqueror installation is missing some files or there's something else not working correctly on your system. Could you please upload a screenshot of your configuration dialog? Also, could you run the following command from your terminal and post the output?

find /usr/share/ -name 'khtml*.desktop'

On a working installation, it should find at least the following files:
html_general.desktop
khtml_appearance.desktop
khtml_java_js.desktop
khtml_behavior.desktop
khtml_filter.desktop

They should be in /usr/kservices5.

As I thought, you're indeed missing a lot of files required to display the full configuration dialog. While the lack of these files shouldn't cause the symptoms you're observing, there could be something else missing which does. Could you please try installing again Konqueror from your distribution package manager, then run again the find command and check whether the missing file have been added? If so, could you try and see if your other issues have been fixed by reinstalling?

i uninstalled, and reinstalled konqueror using synaptic. after reinstalling, i ran the find command, and this came up:

$ find /usr/share/ -name 'khtml*.desktop'
/usr/share/kwebkitpart/kpartplugins/khtmlsettingsplugin.desktop
/usr/share/kservices5/khtml_java_js.desktop
/usr/share/kservices5/khtmlimage.desktop
/usr/share/kservices5/khtml_appearance.desktop
/usr/share/kservices5/khtml_general.desktop
/usr/share/kservices5/khtml_filter.desktop
/usr/share/kservices5/khtmladaptorpart.desktop
/usr/share/kservices5/khtml.desktop
/usr/share/kservices5/khtml_behavior.desktop
/usr/share/webenginepart/kpartplugins/khtmlsettingsplugin.desktop
/usr/share/khtml/kpartplugins/khtmlsettingsplugin.desktop

which, i think, is more what you were expecting to see. and the "Configure Konqueror" dialogue box now looks like this:

https://przxqgl.info/images/221018.02-screenshot.png

which, again, is probably a lot more what you were expecting to see...

and i seem to be able to browse normally, starting from the GUI, so i guess that may have been my problem.
