Sentry Crash Report:

Description Martin Koller 2007-05-19 10:28:05 UTC 
Version:           3.5.6 (using KDE 3.5.6, compiled sources)
Compiler:          gcc version 3.3.5 20050117 (prerelease) (SUSE Linux)
OS:                Linux (i686) release 2.6.18-default

I was browsing http://www.members.a1.net/silentmoods/beispiele/synth.htm
which starts a download of about 4 MBs.
I cancelled this after about 1,5 MBs which still started to play a video. When I closed the now 3 open konq-windows, it crashed with the following bt:

Using host libthread_db library "/lib/tls/libthread_db.so.1".

Comment 1 Carsten Lohrke 2007-10-02 16:57:50 UTC 
Hit this one as well, via

http://www.n-oreal.de/safedataframe.html?fsrc=http://www.n-oreal.de/tft-monitore/samsung/22-zoll/samsung-syncmaster-tft-226cw.html

Konqueror claims the site is loaded in the statusbar, but displays nothing. When hitting the reload button, it crashes reproducibly.

Searching the open bugs for "khtml::HTMLTokenizer::reset" there are a handful of other ones - maybe dupes, didn't check.

Bug #159031 looks like a nice backtrace. 

And:
------- Additional Comment #6 From Maksim Orlovich 2008-07-05 14:00 -------  
This means a child frame is somehow restored before the parent one.

Which I hope is the case here, because the description of triggering the bug in this report is slightly different than all the dups.
Comment 6 Daniel Richard G. 2008-09-11 06:30:38 UTC 
I hit this one too. I opened a new page, which was taking a bit of time to load fully, and hit Back to go to the previous one---boom. Something about Konqueror still parsing the page at that point, possibly?

Comment 7 Daniel Richard G. 2008-09-29 07:50:56 UTC 
Bug 170185 has a test case that easily reproduces this same assertion failure, in the context of going back in the browser history.

(Now I'm getting this crash upon restoration of an autosaved session... oh Konqui, why must you try me so?)
Comment 8 Dario Andres 2009-01-10 03:54:58 UTC 
Bug 180203 may be related to this.
Comment 9 FiNeX 2009-08-29 17:17:38 UTC 
I'm not able to reproduce this crash. Someone is able using KDE 4.3 or trunk?
Comment 10 Martin Koller 2009-08-29 21:00:02 UTC 
As I did not hit this problem since a long time, it would be ok for me to close it.
