Sentry Crash Report:

Description Sandra Large 2008-01-17 09:59:41 UTC 
Version:            (using KDE 4.0.0)
Installed from:    Ubuntu Packages
Compiler:          gcc 
OS:                Linux

After loading up the new beta version of BBC.co.uk, konqueror crashes after imputting your location in the 'Set your location' tab.
When using Firefox which has not problem with this page or tab, a small window pops up after the user has input their location, asking if you wish to save the location that you have put in. It is this which crashes Konqueror every time. 
I am enclosing the backtrace

Patch likely upcoming..
Comment 3 Maksim Orlovich 2008-01-17 18:33:29 UTC 
SVN commit 762684 by orlovich:

Do not emit onchange on synthetic toggling of radio buttons and checkboxes.
That's incompatible, and also led to #155973, crash on the beta BBC's page
location selector, as we have the following scenario:

1. JS sets checked.
2. We do updateFromElement, ask Qt to update the widget
3. The widget emits the change signal
4. The change signal handler does ref() [rc = 2]
5. The change signal handler does onchange(). The event running
causes a detach, which does a deref() [rc = 1]
6. The change signal handler does deref() [rc = 0], so the Render* gets destroyed
7. The common parts of updateFromElement, such as RenderWidget::updateFromElement, etc.,
run on a deleted RenderCheckBox/RadioButton, trying to access deleted
RenderStyle, etc. boom.

BUG: 155973

Comment 4 Maksim Orlovich 2008-01-17 18:47:23 UTC 
SVN commit 762692 by orlovich:

Regression tests for #155973, including onchange emission and the crasher.
Seems like checkbox_onchange covered what I wanted to cover 
for onchange-synthetic.html (Though for radio button only), but clearly it didn't help,
so a little redunancy wouldn't hurt.
