Description Thomas Wouters 2008-09-04 15:28:57 UTC 
Version:            (using KDE 4.1.1)
OS:                Linux
Installed from:    Debian testing/unstable Packages

When surfing to http://bugs.kde.org with javascript error warnings enabled, you'll get an error while loading the page.
Click "Debug" to show the JS debug window.
You'll see the line "document.forms['f'].quicksearch.focus();" on line 91.
Copy/paste this line in the console - or you could enter something different as well - and click "enter".
A new tab will show up with a similar result.
Click "continue" and the previous tab will be shown.
Click "continue" once more and you'll get a crash.

Backtrace:

Application: Konqueror (konqueror), signal SIGSEGV

Comment 5 Gérard Talbot (no longer involved) 2011-08-28 01:23:20 UTC 
I followed the steps and did not crash: WORKSFORME

By the way, I filed bug 279618 because there is a real javascript error in the page with regards to accessing multiple forms (with same name) collection: Konqueror rightly reports the valid javascript error.

I am using
KDE Platform Version: 4.7.0
Konqueror version: 4.7.0 (KHTML rendering engine)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-11-generic-pae i686 (32bits)
Distribution: Kubuntu 11.04
here.

regards, Gérard

Dear Bug Submitter,

This bug has been stagnant for a long time. Could you help us out and re-test if the bug is valid in the latest version? I am setting the status to NEEDSINFO pending your response, please change the Status back to REPORTED when you respond.

Thank you for helping us make KDE software even better for everyone!
Comment 7 Thomas Wouters 2018-10-30 09:09:33 UTC 
Please close this report, I can no longer reproduce the issue.
Comment 8 Andrew Crouthamel 2018-10-30 13:06:22 UTC
