Description L. Jacob 2009-07-09 22:43:12 UTC 
Version:            (using KDE 4.2.4)
Compiler:          gcc version 4.4.0 20090630 (prerelease) (GCC)
 
OS:                Linux
Installed from:    Unspecified Linux

Viewing digg.com, I right click on links and select "Open in new tab".  They load without problem in the background while I view more info at digg.com, loading more links in new background tabs if it's interesting.  I may have 5+ tabs open in the background.  I left click on one of the links to load in the foreground, and Konqueror freezes.  I cannot click buttons or menu items.  I click the 'X' to close and get the following:

Comment 1 Dario Andres 2009-07-09 23:22:08 UTC 
Do you think you could reproduce the crash situation at will?
Thanks
Comment 2 L. Jacob 2009-07-10 00:26:33 UTC 
Yes, problem is observable and repeatable.

Further, this is the final link I clicked on, selecting it by itself, causes Konqueror to crash.

Comment 3 Dario Andres 2009-07-10 00:36:54 UTC 
Here using:

Qt: 4.5.2 (KDE-Qt git commit 46a247a2c9a8c0c4456a02f6a0922d859d88fe76
        Date:   Fri Jun 26 13:45:37 2009 +0200)
KDE: 4.3.60 (KDE 4.3.60 (KDE 4.4 >= 20090706))
kdelibs svn rev. 993248 / kdebase svn rev. 993250
on ArchLinux i686 - Kernel 2.6.30

I can reproduce the crash with the following backtrace:

This seem to be a dupe of bug 195501. Thanks
