Fri Mar 9 00:13:02 UTC 2007

Public bug reported:

using
http://cdimage.ubuntu.com/kubuntu/releases/edgy/release/kubuntu-6.10-dvd-i386.iso

burned on DVD-R.

md5 sum of image read from DVD-R is correct.

doing a default install on:
1)
CPU: ADM Duron 950 MHz
MB Chipset: Via KT133
RAM: 320 MB of SDRAM DIMM PC100

Memtest86+ provided on DVD image shows no problem
System is not overclocked
CPU is not overheated. (45'C)
System works stable under MS Windows for several days in a row

2)
VMWare Workstation 5.0.0-13124 virtual machine
RAM: 128 MB

Steps to reproduce:
1) Do a fresh default installation
2) Set up an internet connection
3) Run konqueror
4) Open any page containing javascript

What happens:
1) konqueror windows disapears
2) KDE Crash handler apears with a message "The application Konqueror (konqueror) crashed and caused signal 11 (SIGSEGV)."

What should happen:
1) Konqueror should display page without crash

Notes:
1) Disabling javascript in Konqeror settings prevents application crashes
2) Changing other javascript options than turn on/off in Konqeror settings does not affects behavior
3) Opera browser installed from file opera_9.10-20061214.6-shared-qt_en_i386.deb downloaded from official Opera's site crashes on javascritp enabled pages too.
4) Disabling javascript in Opera settings prevents application crashes

Suggestions:
1) Problem contains in a file /usr/lib/libkjs.so.1 (a symlink to /usr/lib/libkjs.so.1.2.0) wich is a part of kdelibs4c2 package
2) Opera browser uses system's libraries for javascript
