Description Stephan Johach 2006-03-11 15:44:13 UTC 
Version:            (using KDE Devel)
Installed from:    Compiled sources
Compiler:          gcc 3.3.3 
OS:                Linux

Since my last update from stable branch (svn branch from today) I experience crashes with konqueror. There was no problem with the previous svn version
(last update about one or two weeks ago).

It happened two or three times today while doing a book order on amazon.de.

Here's a backtrace. I am not sure if it always crashes at the same place,
as I only saved the last backtrace.

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

Comment 1 Stephan Johach 2006-03-11 17:25:09 UTC 
Ok, now konqueror crashed when trying to get to bugs.kde.org.

A new started konqueror does not crash, as you can see. This seems somehow random. The backtrace is different from the first.

Comment 2 Maksim Orlovich 2006-03-11 17:38:39 UTC 
Probably something, somewhere is corrupting memory :-(. Undebuggable unless you somehow manage to get a valgrind signature of the cause
Comment 3 Stephan Johach 2006-03-11 20:09:55 UTC

Valgrind trace

I got this valgrind trace when starting konqueror, surfing to amazon.de. But
after a view clicks on my wishlist valgrind suddenly exits due to an assert
when I hit the "back" button.

But there are some traces which look like corrupted memory. I am not sure if I
somehow broke my kdelibs/kdebase build. So if this doesn't point to a real
problem I will do a complete rebuild of kdelibs/kdebase now.
Comment 4 Maksim Orlovich 2006-03-12 15:11:08 UTC 
Yes, can see that, thanks for the report, will investigate
Comment 5 Maksim Orlovich 2006-03-12 15:35:38 UTC 
SVN commit 517900 by orlovich:

Quick fix #123433. Ivor has a better fix than this code, but IMHO it's too 
intrusive this close to 3.5.2 release.
