           Summary: Akregator crashed when using back keyboard shortcut in
                    a tab
           Product: kontact
           Version: unspecified
          Platform: Unlisted Binaries
        OS/Version: Linux
            Status: NEW
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: florian.reinhard at googlemail.com


Application that crashed: kontact
Version of the application: 4.3.0
KDE Version: 4.3.00 (KDE 4.3.0)
Qt Version: 4.5.2
Operating System: Linux 2.6.28-15-generic i686
Distribution: Ubuntu 9.04

What I was doing when the application crashed:
How i triggerd this crash:

1. opened some url from a rss feed
2. clicket on a imageshack link
3. clicked on the image (now just the image, no html opens)
4. used the "back" keyboard shortcut on the image (in my case alt-left)

note: i could not trigger that bug again using these steps
