From bug 257730:
I went to google.com/chrome to download the 64bit .deb version of google
chrome, for my laptop. I click the "Download Google Chrome" button and get to
the "Please select your download package:" page. I select the "64 bit .deb (For
Debian/Ubuntu)" and click the "Accept and Install" button.
I get the rekonq popup window asking "Open
https://dl-ssl.google.com/linux/dir...google-chrome-stable_current_amd4.deb"
I'm given the option to Save As, Open or Cancel. At this point, no matter what
option I click, rekonq crashes.

From bug 253819:
- What I was doing when the application crashed: Was downloading google-chrome
64bit from google website and when hit save it crashed.  Using ubuntu Maverick.

From bug 255125:
-- Information about the crash:
I was working on Drupal administration tasks, and when clicking some button the
browser crashed. This has happened before when clicking some other link or
button, but happens inconsistently (the same button usually works, but then
suddenly crashes).

The problem was in kdewebkit which is part of kdelibs. The issue has been addressed for KDE 4.6 and any future releases of KDE 4.5.x.

Yes, it is. If the backtrace shows the cause of the crash is the following: 

Thread 1 (Thread 0x7ff89055d760 (LWP 23691)):
[KCrash Handler]
#6  0x00007ff8701e2619 in WebCore::QNetworkReplyHandler::forwardData
(this=0x104c8f0) at platform/network/qt/QNetworkReplyHandler.cpp:399

and the user is using QtWebKit that comes as part of Qt 4.7.x, i.e. they did not compile their own version of QtWebKit from git, then the issue has already been addressed in KDE version 4.5.4 and up, not only KDE 4.6. That is the fix has already been back ported...
