Description Neil Skrypuch 2011-03-13 04:04:43 UTC 
Application: konqueror (4.6.00 (4.6.0))
KDE Platform Version: 4.6.00 (4.6.0) (Compiled from sources)
Qt Version: 4.7.1
Operating System: Linux 2.6.36-gentoo x86_64
Distribution: "Gentoo Base System release 1.12.14"

-- Information about the crash:
- What I was doing when the application crashed:

I browsed to http://phoronix.com and before the page loaded completely, Konqueror crashed. This is almost certainly due to some ads on that page, as this wasn't happening as recently as a few days ago, but today it has happened six times in a row now.

Note: This sounds very similar to bug #243739, but the backtrace is different, so I suspect it's not the same bug.

The crash can be reproduced every time.

-- Backtrace:
Application: Konqueror (kdeinit4), signal: Segmentation fault

Comment 3 Tommi Tervo 2011-06-28 09:34:51 UTC 
Possible dupe: https://bugs.kde.org/show_bug.cgi?id=240684
Do you have plugins enabled or not?
Comment 4 Neil Skrypuch 2011-06-28 13:23:05 UTC 
I have kde-base/nsplugins installed, but I don't install Flash, and Java is disabled by default. So, the situation is likely similar to bug 240684.
Comment 5 Vincent de Phily 2011-06-28 18:58:19 UTC 
Using the testcase from bug #240684 I get the same crash (same backtrace) as I pasted in this bug. Disabling plugins fixes the crash. So yes, this looks like a dupe.

New crash information added by DrKonqi

akregator (4.8.3) on KDE Platform 4.8.3 (4.8.3) using Qt 4.8.1

- What I was doing when the application crashed:
Opening tabs in phoronix in the background


- Custom settings of the application:
I've recently set Left Mouse click on "Open Background tab" instead of "Open tab".
Maybe this is not related with the bug

New crash information added by DrKonqi

akregator (4.8.4) on KDE Platform 4.8.4 (4.8.4) using Qt 4.8.2

- What I was doing when the application crashed:

I opened a Phoronix article from Akregator. The article started to load with a window that said "close advertisement". Before I could close the ad, Akregator segfaulted.

- Unusual behavior I noticed:

After I restarted Akregator, I noticed that the article did not show in the list of unread articles--perhaps this was refreshed.

Valgrind log.

Find attached a valgrind log, as Tommi said valgrind runs didn't make akregator(in my case) crash.

Akregator 1.6.6 on KDE 4.8.3. Qt 4.8.2.

This is what I think it's the relevant part:

New crash information added by DrKonqi

kontact (4.10.2) on KDE Platform 4.10.2 "release 553" using Qt 4.8.4

The crash happened when I tried to open a kde-apps.org application page in Akregator. Opening the page in Konqueror now doesn't cause the crash.

Surfing with Akregator.  Does this have to do with an ATI/mesa bug and the Phoronix ad system during changes to alpha in the browser?
Comment 28 Justin Zobel 2020-12-14 01:38:14 UTC 
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.
Comment 29 Marek Paśnikowski 2020-12-14 01:45:54 UTC 
It's been months since I last used KDE and even longer since I last used konqueror. I am not able to test.

Comment 30 Donald 2020-12-14 01:55:31 UTC 
I just tried to trigger the same bug I reported 8 years ago from Akregator. Using Akregator 5.13.2 tonight,I had no problem opening a Phoronix article.

Works for me,

Donald
Comment 31 Christopher Heiny 2020-12-14 03:08:06 UTC 
I'm able to browse Phoronix w/Konqueror 20.08.3 on Fedora 32.

Sorry, I'm not using konqueror for a few years (>5)

Several users have confirmed now working, setting to resolved. If any other users are still experiencing this issue feel free to reopen.
