Description Oliver Putz 2008-08-10 15:48:28 UTC 
Version:           4.1.00 (KDE 4.1.0) (using 4.1.00 (KDE 4.1.0), Gentoo)

OS:                Linux (i686) release 2.6.25-gentoo-r7

I was browsing through the bugs of a query on bugs.kde.org. When I clicked next on one bug, konqueror all of a sudden crashed with the backtrace below. So far I was not able to reproduce this crash.

Application: Konqueror (konqueror), signal SIGSEGV

Not sure if it helps, but I *think* the next bug on my list (the page that was going to be loaded next) was https://bugs.kde.org/show_bug.cgi?id=163736
Comment 2 Oliver Putz 2008-10-31 18:59:20 UTC 
I just ran into this bug again. This time it was when I opened a link in a mail from within kmail. More precisely:

1) Clicked on a link from mail A (https://bugzilla.novell.com/show_bug.cgi?id=433239) that opened in a new konqueror window
2) Went to another mail and clicked on a link in that mail (http://bugs.kde.org/show_bug.cgi?id=173160) and then kontact crashed with the backtrace below

Both mails were only opened in the "preview" pane (*no* double click on the mails to open them in a new window)

Application: Kontact (kontact), signal SIGSEGV

Comment 3 Oliver Putz 2009-06-26 10:58:24 UTC 
Happened once again when clicking on a link in a mail opened in the preview pane in kmail. This time its a backtrace from KDE-4.2.4

What I was doing when the application crashed:
I was trying to open a page in the Opera browser from an e-mail I received.
Unfortunately, I was having no success -- instead, Kmail chose to crash.

 Somehow we have a range selection with a null base....

Bug 223588 got another (sometimes) reproducible testcase:
What I was doing when the application crashed:
When I clicked several on the image (http://smu.edu/totw/totwmain.jpg) on the
website http://smu.edu/totw/ konqueror crashed.

Bug 223588 comment 1 has a complete KDE SC 4.5 backtrace.

OK, so it sets an extent on a null one - so we have an empty 
selection/null base, and d->editor_context.m_beganSelectingText is true.

SVN commit 1079105 by orlovich:

Make selection normalization more robust, so we don't 
blow up an crash extending from an empty base.
(Important, since potentially repsonsible for some kmail 
 crashes => will backport for 4.4)

BUG: 168849
