^^^^^^^^^^ 
This says the crash is occured inside your graphics driver. Can you reliably reproduce this crash ? Also did the crash occur while you are browsing for the file to print or when you closed the browser ? The rest of the crash log seems to indicate that the browser window was being closed when the crash occurred.

New crash information added by DrKonqi

konqueror (4.8.00 (4.8.0 "release 462") on KDE Platform 4.8.00 (4.8.0 "release 462" using Qt 4.8.0

- What I was doing when the application crashed:

I did nothing for ~20 seconds, konqueror did not crash in response to some user interaction, but without receiving any input from me. Unfortunately the problem is not reliably reporducable.

Comment 3 Dawit Alemayehu 2012-03-12 02:14:01 UTC
Git commit da87f110bbe9bb6a59286ea848e9d8a829361d8b by Dawit Alemayehu.
Committed on 12/03/2012 at 02:48.
Pushed by adawit into branch 'master'.

Meant to use QPointer not QScopedPointer.

Note that the crash reported in the bug # below was supposed to be addressed by
the original commit db0ee97f. However, QScopedPointer causes the same problems
as using a plain pointer or creating the print dialog on the stack. For further
detailsi details, read http://blogs.kde.org/node/3919.
