The backtrace looks good, but before we can pass this on to the KHTML team we'll need a bit more info. (so that they don't ignore it)
Does this crash happen in a reproducible fashion? Which website causes this crash?

Hi Jonathan!

Yes: Konqueror crashes very often on this site (reproducible). - I don't know if it is always the same reason - and it seems to be a bug in the website, not only in Konqueror. Opera (10.00 Beta) also crashes here. Firefox seems to work, but gets errors. (I am not used enough to firefox to copy the bug-messages... :( )

This is what I did on the homepage.
I clicked on a smiley that should produce an ascii equivalent for the chat.
Konqueror here now also crashes immediatly while trying to use the last session on restart.

This is the chat:
/*
 * @package AJAX_Chat
 * @author Sebastian Tschan
 * @copyright (c) Sebastian Tschan
 * @license GNU Affero General Public License
 * @link https://blueimp.net/ajax/
 */

I only installed it locally and it is not always available on the net. - Only per request by e-mail.

This is what the commandline said:

$ konqueror
<unknown program name>(21211)/ main: 2 - parseCommandLine
<unknown program name>(21211)/ main: 3 - create KApplication
Disabling the GTK-Qt Theme Engine for "/usr/bin/nspluginviewer"
KCrash: Application 'konqueror' crashing...

Hi there!

Thanks for reporting this bug! Your bug seems to be a problem with the KDE program itself, and not with our KDE packages. But don't worry! This issue is being tracked by the KDE developers at: http://bugs.kde.org/show_bug.cgi?id=206022
Once fixed in KDE, it will be included in Kubuntu once the KDE version the fix is in in reaches Kubuntu.

Thanks!
