Application: konqueror (4.8.5 (4.8.5))
KDE Platform Version: 4.8.5 (4.8.5) (Compiled from sources)

Operating System: Linux 3.5.3-1.fc17.i686 i686
Distribution (Platform): Fedora RPMs

-- Information about the crash:
What I was doing before the crash happened, you asked? Let's see...

Oh yeah, now I remember! I wanted to install an old Lexmark x75 All-in-One Printer/Scanner. I went online to search for Linux Fedora 17 Drivers for the Lx75P/S.
I stopped using Firefox web browser and stayed with Konqueror to test something out. It might have to do with being a Netscape thing. Anyhow, I was reading an article about the drivers...let me recheck Konqueror's browser History...

Roughly @ about 18:56 on 09/06/2012

Last thing I recalled working on was getting out of the Google Groups before the crash. I clicked on a referring link from either one of these HTTP websites after doing a search for 'lexmark x75 scanner drivers Linux' from Google Search Engine:
- http://www.openprinting.org/printer/Lexmark/Lexmark-X75
- http://home.online.no/~enrio
- http://lexmark-x74-x75.soft32.com/
- https://www.linux.com/community/forums/drivers/lexmark-x75-all-in-one-driver
- http://support.lexmark.com/index?page=content&locale=en&productCode=&segment=DOWNLOAD&actp=CONTENT&userlocale=EN_US&id=DR15629

That's what I was doing according to the browsers history. I have included the crash report before for your referencing.
