Description David Palacio 2008-09-01 14:12:23 UTC
Version:           4.1.00 (KDE 4.1.0) (using 4.1.00 (KDE 4.1.0), Debian packages)
Compiler:          cc
OS:                Linux (x86_64) release 2.6.25-2-amd64

How to reproduce:

1. Open http://www.nagomiko.net/
2. Open a link in the left side
3. Go back in history

Found this behavior in Debian's  precompiled packages and 4.2 compiled sources (r855347)

1st part of a test case (HTML page inside a frameset)

This HTML page (containing a frameset) crashes Konqueror when you go back to it

I can confirm the crash with 4.1 and trunk rev. 855891. I get a different signal (SIGABRT) and a slightly different backtrace for both the original page and this reduced testcase. All frames starting from #12 in comment 2 appear in my bt as well, though.

How to crash Konqueror:
1. Load the test case.
2. Go to some other page, e.g., http://www.kde.org/.
3. Click "Back".

Seems to be due to the 'document.write(parent.document.referrer);' command in the frame inside the frameset. 

In Konsole, a failed assertion is reported:

konqueror: /home/kde-devel/kde/src/KDE/kdelibs/khtml/html/htmltokenizer.cpp:164: void khtml::HTMLTokenizer::reset(): Assertion `m_executingScript == 0' failed.
Comment 6 Daniel Richard G. 2008-09-29 07:44:56 UTC
That last assertion failure is basically bug 145666. It happens in cases like e.g. restoring an autosaved session, so it's not just about going back in the history. (Test case crash and autosave crash both confirmed as of r865565)
Comment 7 Sebastian Sauer 2008-10-26 23:00:28 UTC
maybe dup of bug #170185 or bug #167966 - all 3 are *not* reproducable for me with KDE trunk.
Comment 8 Frank Reininghaus 2008-10-26 23:12:28 UTC
(In reply to comment #7)
> maybe dup of bug #170185 or bug #167966 - all 3 are *not* reproducable

You probably meant bug 173066 and bug 167966. All these going back crashes are probably related, and I've also noticed that I can't reproduce these any more since a week or so. Maksim told me it's timing-sensitive and therefore not always easy to reproduce. The problem is that the page you're trying to go back to has iframes, and an iframe which is already restored tries to access its parent which is in some cases not fully restored yet.
Comment 9 David Palacio 2008-10-28 20:44:19 UTC
Testcase still crashes as of revision 877144 from trunk/
Comment 10 David Palacio 2008-10-28 20:45:58 UTC
Forgot backtrace (r877144)

I've this on http://www.wetteronline.de/Berlin/Berlin.htm :

2) go back -> crash

But my backtrace is different:

SVN commit 926130 by orlovich:

Remove this hack; I don't want it anyway, and having it can cause the going-back buginess to crash;
with it gone is will 'merely' lead to JS errors, so the restore code for frames still needs rework,
but at least it removes the major stability issue.

I still have the same crash with current 4.2 branch (4.2.4).
Comment 40 Olivier E. 2009-07-05 10:49:43 UTC
The same crash happens to me with KDE 4.3 RC1
Konqueror crashes when I click back to a phoronix.com page.
No problem when I browse nagomiko.net and bugs.kde.org/attachment.cgi?id=27164
